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

• rough

• plane

• shiny

• plain

The illustration shows a light ray striking an object.
In the illustration, the light ray striking the object is-

• absorbed
• stopped
• reflected
• refracted

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 enlarged.

• 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.

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

• can travel in curved lines

• bends when it passes through water

• makes the water denser than the glass

• reflects the pencil on the water's surface
