Introduction

Summary

The Doppler Effect is the change in the apparent frequency of a wave as the observer and source move towards or away from each other.
If the source moves at the same speed as the sound that it emits, it “breaks the sound barrier”. This speed is called Mach 1.

Goals

• To illustrate the Doppler effect and a shock wave.
