Mini-Quiz: Dispersion of Light

by Ron Kurtus

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

1. Which color has a shorter wavelength: green or orange?



Both colors have the same wavelength

2. Can you see a rainbow when facing the Sun?

Not if the Sun is too bright

There are no rainbows if the Sun is shining

The Sun must be behind you

3. What makes some cameras more expensive?

They have specially designed lenses to eliminate chromatic aberrations

They have lenses that create beautiful rainbow colors

They use plastic lenses, because they weigh less

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.

Have courage
