How to Solve Doppler Effect Problems in Physics

Doppler effect is the reason why a car has a slight change in sound as it passes you. As objects get closer, they appear to sound higher pitched than normal, and when they go away from us, they sound lower pitched than normal.

I give the equation for doppler effect, and how to use all the variables. Then we do some practice problems.
