When light reflects off a completely smooth, shiny surface it has _____________ reflection.

• regular

• diffuse

• transmission

• divergent

The Law of Reflection:
The angle of incidence is _________ the angle of reflection

• bigger than

• equal to

• smaller than

The type of mirror in the picture is a __________ mirror.

• convex

• plane

• concave

• plain

In the illustration, the light ray striking the object is

• absorbed

• transmitted

• reflected

• refracted

A student placed a pencil in a cup of water. The pencil appears broken because light

• can travel in curved lines

• refracts when it passes through water

• makes the water denser than the glass

• reflects the pencil on the water's surface

When you are looking at the child, why does the lower part of the child appear so much different in size from the upper part?

• The light rays that travel through water and then into air are refracted.

• The light rays that travel through water and then into air are magnified.

• The light rays that travel through air and then into water are reflected.

• The light rays that travel through air and then into water are absorbed.
