Doppler Effect Exercise Instructions
When you access the animation, you will see the default settings start with object speed = 50 and wave speed = 80. In this case, the wave speed represents the speed of sound. Therefore, if the object speed is increased to 80, you are about to exceed the speed of sound.
1. Click play and observe the wave fronts. They should look like Figure in text.
2. Click Rewind << and set object speed at 80, which puts the object speed equal to the speed of sound.
3. Click play and observe how the wave fronts have all compressed to the point that it looks like one wave in front of the object.
4. Click Rewind << and set object speed to 85, which puts the object speed higher than the speed of sound. The moving object has broken the sound barrier.
5. Click play and observe the shape of the wave form and compare it to Figure in the text. You can click on the pause button to see the three dimensional effect of the bow wave.
6. Click Rewind << and set object speed to 100, well beyond the speed of sound.
7. Click play and then click on the pause button to see the three dimensional effect of the bow wave.
At this point, new sound waves are generated (ahead of/behind) the source and a cone shaped shock wave forms. Circle the correct answer. https://www.upscale.utoronto.ca/GeneralInterest/Harrison/Flash/ClassMechanics/DopplerWaveFronts/DopplerWaveFronts.html
