Mini-Quiz: Conventions for Doppler Effect Equations

by Ron Kurtus (8 November 2012)

Take this Mini-Quiz to check your understanding of the lesson material.



1. Why should there be a convention in direction of motion?

To add to things you must remember

It really is not necessary

To avoid confusion in equations

2. Why is there a restriction that the velocity of the source is less than the wave velocity?

The Doppler Effect does not work at velocities greater than wave velocity

The restriction is to make the equations easier to memorize

No one is really sure why there is such a restriction

3. What is the unit for the period of a wave?

Hz

Meters

Seconds

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
