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

• A

• B

• C

• D

This lake's water is so calm that it looks like a huge mirror on the ground. What property of light creates this illusion?

• Refraction

• Reflection

• Transparency

• Opaqueness

Sammy did an experiment using a flashlight and three index cards. The cards all had holes in them at the exact same spot. The light went through all of the holes and then hit the wall behind the cards. What Sammy want to prove was?

• Index cards come in pretty colors.

• Flashlights are able to burn holes in paper.

• Light travels in straight lines.

• Light cannot squeeze between tiny holes in paper.

• Angle of Reflection

The ray that bounces off the mirror.

• Angle of Reflection

• Incidience Ray

• Reflected Ray

• Angle of Reflection

The angle between the incident ray and the normal. (X on the diagram)

• Angle of X-Ray

• Angle of Incidence

• Angle of Normal

The angle between the reflected ray and the normal (labelled Y on the diagram).

• Angle of Incidence

• Angle of Reflection

• Angle of Normal

• Angle of Light

An imaginary line that is drawn at a right angle (90 degrees) to a mirror (Green line)

• Reflection Ray

• Normal

• Incidence Ray

• Light Ray

If the angle of incidence in the diagram is 80°, the angle of reflection will be:

• 10°
