nals through waves. Speech means production of sound waves in air and hearing amounts to their detection. Often, communication involves different kinds of PHYSICS. 364 satellite. Detection of the original signal will usu- ally involve these steps in reverse order. Not all waves require a medium for their propagation.
The topics for the second part of our physics class this quarter will be oscillations and waves. We will start with periodic motion for the first two lectures, with our . x(t)=(Acos?)sin(?t)+(Asin?)cos(?t). (11). This form for x(t) can be written in a more convenient way. At t = 0, x0 ? x(0) = Asin?: x(t)=(Acos?)sin(?t) + x0cos(?t).
Wave Motion WHAT IS A WAVE A wave is a disturbance that travels or propagates and transports energy and momentum without the transport of matter. The ripples on a pond, the sound we hear, visible light, radio and TV signals are a few examples of waves. Sound, light and radio waves provide us with an effective

Module 3.1 WAVES. DOPPLER EFFECT FOR SOUND. DOPPLER EFFECT - motion related frequency changes. Christian Doppler was an Austrian . 11. Example. A train whistle is blown by the driver who hears the sound at. 650 Hz. If the train is heading towards a station at 20.0 m.s-1, what will the whistle sound like to a
