SC.7.P.10.2 (Refraction, Reflection, Absorption)

When a pencil is placed in a glass of water, the pencil appears broken at the surface of the water. This is because:

• Light wave speeds up when it moves from air to water
• Light wave slows down when it moves from air to water
• Light wave stops when it hits the water
• There is no change in the light wave's speed 

The pictures shows what a student observed when he looked through a hand lens at a penny.
What happens to light passing through a hand lens that makes the image of the penny appear larger? The light is-

• absorbed
• reflected
• refracted
• stopped

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

• absorbed
• stopped
• reflected
• refracted

A material that reflects or absorbs all the light that strikes it is

• Opaque
• Transparent
• Translucent
• Concave

The bouncing off of light rays from the surface of an object such as a mirror or other shiny surface is called:

• mirror
• laser
• reflection
• refraction

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 reduced.
