Week 10: Post lab Questions – Environmental Solutions I (25 points)

Scientists use an instrument called a spectrometer to quantitatively determine the amount of light absorbed by a solution. The primary inner parts of a typical spectrometer are described below. The spectrometer has a light source that emits white light containing a vast mixture of different wavelengths of electromagnetic radiation. The wavelength of interest is then selected using a monochromator (“mono” meaning one and “chromate” meaning color) and an additional exit slit. The separation of white light into different colors (wavelengths) is known as diffraction. The selected light then reaches the sample and depending on how the light interacts with the chemical compound of interest, some of the light is absorbed and some passes straight through. By comparing the amount of light entering the sample (P0) with the amount of light reaching the detector (P), the spectrometer is able to tell how much light is absorbed by the sample.

Define all of the bold words in the previous paragraph. (4 points)

Spectrometer: an optical instrument that can detect spectral lines. It measures it’s wavelength and intensity.

Quantitatively: something that is part of the metric system, can be given a numerical value.

Electromagnetic radiation: radiation that includes radio waves, visible light, x-rays and gamma rays, where the magnetic and electric fields vary at the same time.

Monochromator: an optical instrument that transmits a mechanically selectable narrow band of wavelengths of light or other radiation which is chosen from a wider range of wavelengths that are available at the input.

Diffraction: a process where a beam of light or another system of waves is spread out because they pass through a narrow aperture or across an edge. Usually accompanied by interference between...

The boy just smirked at the lady and gave her his deadly stare. He抣l grow up to be a handsome guy. Naku ang popogi ng mga anak mo Mare. Syempre kanino pa ba magmamana ang mga yan? The other lady told the other one kaya nagtawanan sila. What抯 their name? Yung kinurot mo si Tamako and the one playing is Tamadao. C抦on boys, greet your Tita Kath. Hi Tita Kath. The boy named Tamadao, stopped playing and kissed the cheek of the lady named Kath. Ohh, you are so adorable. And she kissed his cheeks. Si Tamako naman nakatingin lang sa kanila. Tamako.. Okay, okay. I抦 greeting her. Hi Tita Kath. And when he was about to kiss her, the baby in her tummy kicked. Ow! What抯 wrong baby? Why did you kick Mommy? Sabi nung Kath while massaging her bulging tummy. She is 9 months pregnant and anytime soon, she抣l deliver her baby. Your baby is epal. I bet she is ugly. Napatingin ang dalawang babae sa kanya. Tamako! His Mom scolded him. It抯 okay Mare. But how did you know that she is a girl, handsome boy? The boy just smirked. Maybe she likes you that抯 why she kicked me.
