20.01 The particles in the pulse do not travel from one place to another. The particles are like people trying to make a wave in a football stadium. Each person stays in their seat, waiting for their turn to briefly stand up and then sit back down without moving to any other seats or anywhere else. 20.03 If the period of a wave is 0.20 s, it means each particle in the wave completes one vibration in 0.20 s. The wave does not continue to travel for 0.20 s before stopping; a period is the time it

Noise may be defined as any unwanted form of energy tending to interfere with the proper and easy reception and reproduction of signals. It may be subdivided according to type, source, effect, relation to the speaker, depending on circumstances. 1. External Noise. * Atmospheric Noise – consist of spurious radio components distributed a wide range of frequencies. Majority of these radio signals come from the natural sources of disturbance generally called static. * Extraterrestrial Noise
