White light is made of_______.

• A mix of red and yellow
• A mix of black and purple
• A mix of all the primary colors (red,green yellow, indigo, etc)

Refraction is when light__________.

• Is bounced by an object or material.
• Changes speed as it travels in different materials which causes bending.
• When light speeds up to over 300,000 km/s

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

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.

What is this called?

• refraction
• reflection
• reconstroction
• retraction

Which of the following is not an example of refraction?

• background scenery on water's surface
• light passing through a raindrop
• a "broken" straw in a glass of water
• a shallow looking pool
