Mini-Quiz: Doppler Effect Equations for Light

by Ron Kurtus (revised 15 April 2013)

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



1. What is the red-shift frequency equation?

fr = f(1 − vr/c)

fr = f(1 + vr/c)

fr = f(1 − c/vr)

2. If the velocity of an object towards you increases, what happens to the wavelength of the light?

It turns blue

No change is noticed

The wavelength is less than the original spectral line

3. If the observed wavelength λr equals the emitted wavelength, what is vr?

c

c/2

0

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.


Think of some clever new ways of doing things
