A light ray hits a plane mirror. Which ray correctly illustrates the law of reflection?

• A

• B

• C

• D

A lens is:

• a transparent object that refracts light rays

• a source of light

• an opaque object

• a type of mirror

The shape of a convex lens is different from a concave lens in that:

• A convex lens is thicker at the center and thinner at the edges, while a concave lens is thinner at the center and thicker at the edges.

• A convex lens is flat on both sides, while a concave lens is curved on both sides.

• A convex lens is always smaller than a concave lens.

• A convex lens is made of plastic, while a concave lens is made of glass.

Which optical devices will form real images?

• concave mirror and convex lens

• concave mirror and plane mirror

• plane mirror and convex lens

• plane mirror and concave lens

Which type of images can be projected onto a screen?

• real images, only

• virtual images, only

• both real images and virtual images

• neither real images nor virtual images

What is the best explanation for this phenomenon? (A straight glass rod appears to bend when placed in a beaker of water, as shown in the diagram below.)

• The water is warmer than the air.

• Light travels faster in water than in air.

• Light is reflected at the air-water interface.

• Light is refracted as it crosses the air-water interface.
