Lesson 2: Reflection and Mirrors

Multiple Choice

When a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence.

• Law of reflection

• Newton's laws

• Gravity

• Darwin's theory

Multiple Choice

In the diagram, which letter represents the angle of incidence?

• A

• B

• C

• D

Multiple Choice

What is the line MN called in the given diagram?

• incident ray

• reflected ray

• reflecting surface

• normal

Multiple Choice

When light reflects off of a completely smooth surface it is called:

• Diffuse Reflection

• Optical Reflection

• Smooth Reflection

• Specular Reflection

Multiple Choice

Why does the reflection on the right appear fuzzy?

• individual light rays are not following the Law of Reflection.

• the rough surface is causing each light ray to go in different directions

• some light rays are absorbed by the water

Multiple Choice

If a bundle of parallel incident rays strike a rough surface, why do they each scatter in a different direction?

• The Normal is not parallel to the surface.

• The Normal is not perpendicular to the surface.

• Since the Normal is the same for each light ray, they will all reflect the same direction.

• Since the Normal is different for each light ray, they will reflect in different directions.

Multiple Choice

Which surface would most likely result in diffuse reflection?

• a glossy sheet of paper

• A calm lake

• a mirror

• a wool sweater

Multiple Choice

Which diagram represents diffuse reflection?

• A

• B

• C

• D

Multiple Choice

What is reflection?

• Reflection is the bouncing  of light off the surface that it strikes on.
• Reflection is the absorbing of light off the surface that it strikes on.
• Reflection is the bending of light off the surface that it strikes on.
• Reflection is the scattering of light off the surface that it strikes on.
