This simulation lets you determine set the speed of a moving object relative to the speed of sound (the Classical button) or light (the Relativistic button). Yes, the Doppler Effect works with light too, but you can wait until you take college physics to explore this phenomenon. If we could see them, what do you expect sound waves to look like coming from an object that isn't moving? Would you expect the pitch of the sound coming from this object to be affected? Let's investigate. Leave the button on Classical and using the "speed" slider set the speed of the object at 0. Press the "start" button. Adjust the "speed" slider to 0.5 and press the "start" button. Notice the pattern of waves that is produced. How
would you describe the resulting wave pattern? Would the pitch of
the sound produced by the object be equivalent on all sides?
