Doppler activity

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? Using flip grid, take a movie, and/or some stills and annotate. 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
