What exactly is the electromagnetic spectrum?
Is a continuous range of wavelengths, which includes gamma rays, ultraviolet waves and other forms of electromagnetic radiation.
How does the issue of scarcity and interference relate to the electromagnetic spectrum?
The spectrum is considered scarce because of the limited number of frequencies for operation and two parties cannot broadcast on the same frequency in the spectrum. Interference not only can be caused by broadcasters but by natural phenomenons like thunderstorms. Another factor, which can attribute to interference is one known as Intermodulation. This happens when two or more frequencies affect each other’s transmission.
What key decision did Congress make in 1927 in regards to the electromagnetic spectrum?
In 1927 Congress declared that there could be no private ownership of the airwaves or spectrum; they were now considered public and could only be used with the approval and permission of the government.
Who would own the electromagnetic spectrum?
The airwaves were considered publicly owned.
Who would be responsible for allocation of the spectrum and who would it be controlled by?
Congress created a five member commission who now had the responsibility for allocation of the spectrum and controlling these allocations.
What agency would be responsible for giving out licenses and was it free of charge or was it for a fee?
What Congress considered a balanced five member commission which is today know as the Federal Communications Commission had the responsibility for issuing licenses for operating on the spectrum at no charge but only for a period of three years.
What were the standards for assessing what broadcasters were “worthy” enough to receive a license?
What exactly were these licenses for?
These licenses were issues, allowing you to broadcast on a portion of the spectrum.
For use of a portion of the electromagnetic spectrum?
But what does that mean?
It meant that you now had the right to broadcast on a specific frequency in the spectrum.
Do you agree or disagree with this method of “managing spectrum”, why or why not?

Political Spectrum

...The Political spectrum is a system of classification of different political positions upon one or more. On the. Demo metric axes it symbolizes independent political decisions.

Next is Moderate, moderates hold a belief that falls between liberal and conservative views including somewhat similar views from both conservative and liberal. The Conservative stance wants to keep in place. The economic, political, and social structures of society, so no change in society. Lastly on the spectrum is reactionary. The reactionary part if this spectrum seeks extreme change to resort society to an earlier, more conservative state.

Electromagnetic Spectrum

...The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation.[1] The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. Types of Electromagnetic Spectrum: Radio-The wireless transmission through space of electromagnetic waves in the approximate frequency range from 10 kilohertz to 300,000 megahertz. Micro wave-An electromagnetic wave with a wavelength between that of infrared and short waves (one millimeter to one meter).Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes. infrared radiation-Invisible radiation in the part of the electromagnetic spectrum characterized by wavelengths just longer than those of ordinary visible red light and shorter than those of microwaves or radio waves. Visible radiation( light)- electromagnetic radiation that can produce a visual sensation. Ultraviolet-Of or relating to the range of invisible radiation wavelengths from about 4 nanometers, on the border of the x-ray region, to about 380 nanometers, just beyond the violet in the visible spectrum.X-rays- Gammo rays-Electromagnetic radiation emitted by radioactive decay and having energies in a range from ten thousand (104) to ten million (107) electron volts. Dangers for using any EM radiation: EM radiation impinges upon a conductor, it couples to the conductor, travels along it...

Autism Spectrum Disorder

...Surname 1 Name Course Professor Date Autism Spectrum Disorder All around the world, there are several children and even grow ups that have or suffer from autism. Unfortunately, it is a condition that is not easily detectable especially in children. Most people either do not understand the condition that manifests itself in children or take it for something else all together. For the families that are fortunate enough to identify the condition in children, they at most times have no idea at all on how to handle the child. Most people have misunderstood autism and taken it as insanity in children. It is therefore, necessary to demystify the misinterpretations in most people and make them aware of the condition, and how to handle it when a child is found to be autistic. Autism is a spectrum of closely related conditions or disorders which all have symptoms of a shared core. Every child said to be on the autism spectrum disorder has to some degree problems with communication, social skills, flexible behavior and empathy. However, the degree of disability and symptoms combinations varies enormously from one child to another. Surprisingly, children with the same diagnosis may be very different when it comes to abilities and behaviors. It is vital to note some few facts about autism. Autism is not contagious and is not acquired through environmental contact. It is a neurological disability presumed to be present from birth and apparent before the age of three in a child. Even though...

...Autism spectrum disorder (ASD) Autism spectrum disorder is a really interesting disorder to learn. In 2012, approximately 1 in 88 child in the United States was diagnosed with Autism by the Center for Disease Control and Prevention Autism and Developmental Disabilities Monitoring Network. This is a tremendous increase compared to the reporting’s in the 1980’s; it was reported as 1 in 10,0000. ASD’s are a “spectrum disorders”, which means it affects each person in distinctive ways, and can also range from mild to severe circumstances. This disorder is a group of developmental disabilities that cause a great social, interaction and ways someone responses to challenges. Therefore these people with similar characteristics handle cognitive information in a different way than other people. Since the symptoms of autism spectrum disorder differ on each individual. Children with ASD fall into three categories such as; social defacement, hard time with communicating, and rhythmic behaviors. Social difficulties are common with all ASD disorder. Social impairment has an effect on a child’s everyday life. For example, a child will not be able to respond to parent or others by 1 year of age. The child might like solitary better and not play with others, has facial expressions that are improper, does not know the difference of personal boundaries and also may have trouble understanding about their own feelings etc. Let’s say that a typical child starts to understand and learn things as...

Political Spectrum Essay

...When examining my own ideology, I consider myself to be a moderate centrist. In general, my opinions on the economic policy, as it pertains to conservatives. However, I share my views with the liberals when it comes to their social policy. After looking at the political platform of both liberalism and conservatism and comparing my views on the issues, which are: lower taxes, welfare reform, free market, abortion, same-sex marriage and euthanasia; I found out that I am a centrist. I share my views with Jean Jacques Rousseau on the idea that “man is born free, but everywhere he is in chains”. Humans are living in a state of innocence with nature before being corrupt by society. He philosophizes that a human begins feeling self-confident and is a mentally healthy being, but once subjected to the expectations, condemnations, and influences of society the person is no longer healthy and begins to experience a loss of confidence.  Society causes a person to become prideful and forge ahead for unrealistic goals.  Thereby, losing one's own self and as a result loses freedom.  The person has been chained by social corruption. In addition, Rousseau states that man became more and more corrupt and degenerate as he became a “social animal”. However, as Aristotle said “Man is by nature a social animal”. Therefore, as nature is corrupted by society, our government is also corrupt. In today’s society, cheating, lying, and scandal is all part of everyday life, so it is no surprise that these...

Autism Spectrum Disorder (ASD)

...Autism Spectrum Disorder (ASD) is attributed to various conditions distinguished by complications with “social skills, repetitive behaviors, speech and nonverbal communication, as well as unique strengths and differences” (“What Is Autism?”, 2012). This is the reason why the term “Spectrum” is used, it “reflects the wide variation in challenges and strengths passed by each person” (“What Is Autism?”, 2012). ASD does not come in one form, but varied types caused by distinct blends of genetic and environmental influences (“What Is Autism?”, 2012). ASD can be diagnosed by 18 months, but symptoms usually arrive at 2 and 3 years of age. There is currently no medical test that diagnoses ASD, but behavioral evaluations that are done by trained physicians...

...Autism Spectrum Disorder (ASD) is an incredibly complex condition that affects each individual differently, primarily depending on what point of the spectrum they reside. Despite the differences, there are some overarching themes that can be discussed to better understand how ASD affects an individual’s life. By understanding topics ranging from social life and bisexuality to behavioral intervention and comorbidities, we can become better advocates and supporters of individuals living with ASD. Beginning early behavioral intervention shortly after a diagnosis can be incredibly effective in strengthening positive living habits, provided that implementation is consistent and rigorous.

7 Regions of the Electromagnetic Spectrum

...The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. There are 7 regions in the electromagnetic spectrum and they are gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves. All types of electromagnetic radiation are transverse waves and they all travel at the same speed in a vacuum. The regions of the electromagnetic spectrum are explained below in order of increasing wavelength and decreasing frequency. Gamma Rays (γ-rays) Gamma rays have the lowest wavelength but the highest frequency in the electromagnetic spectrum. They are produced by radioactive atoms in nuclear explosions. Gamma rays are highly penetrating rays and can kill living cells, which due to this it is used in medicine to kill cancerous cells. However, they can also kill healthy cells which could lead to cancer. Gamma rays are also used to kill bacteria in food and to sterilise surgical instruments. X-rays X-rays are used to produce photographs of bones to check if for any damages or fractures. They can also be used to check metal components and welds or any other damage. The earths atmosphere is too thick for x-rays to enter, so x-ray astronomy has to be done in space. X-rays come from fast electrons that decelerate after striking something. Advantages of x-rays are they can be used to check if anyone has any broken bones in their body. Disadvantages are that x-rays can cause mutations in the DNA, they can cause cancer and they...
