Reflection and Waves Quiz

What is reflection?

• When a wave is absorbed by an object

• When a wave passes through an object

• When a wave strikes an object and bounces off

• When a wave is refracted by an object

What does the Law of Reflection state?

• The angle of incidence is always greater than the angle of reflection.

• The angle of incidence is always equal to the angle of reflection.

• The angle of incidence is always less than the angle of reflection.

• The angle of incidence is unrelated to the angle of reflection.

Why do sound waves tend to diffract better than light waves?

• Because they are faster

• Because they are much larger

• Because they are more colorful

• Because they are quieter

What is the effect of a larger object on wave diffraction?

• It increases diffraction

• It decreases diffraction

• It has no effect on diffraction

• It changes the wave's color
