Concept 3.4 Refraction

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

• always travels in a straight line.

• bends when it passes through water.

• makes the water in the glass evaporate.

• reflects the pencil on the water's surface.

What type of lens is wider in the middle than on the edges?

• Concave

• Convex

• Objective

• Ocular

What type of lens is thinner in the middle than at the edges?

• Convex

When light passes through a convex lens, it does this.....

• Diverge, or spread apart

• Converge, or come together

• Reflect, or bounce off

• Create a rainbow
