Doppler effect
Today you need to create a model of the Doppler effect.
You will need strips of paper, scissors glue.
Create a set of concentric circles as shown below
Once you have created this you need to take a photo and annotate it with the following
The sound source
The wave front
The wave length
Now place a pen in the middle of the concentric rings and move the rings around. What happens? Take a still and annotate the image. Identify the above again.
Explain what happens at the front and back of the rings when you are moving them. How is this an model of the Doppler effect
