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

• absorbed
• stopped
• reflected
• refracted

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

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

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.

How many colors are in the rainbow?*

• Nine
•  Five
• Seven

According to Willebord Snell, light passing from air to glass will cause the light to

• maintain its original speed 
• accelerate while it is in glass
• increase its speed
• reduce its speed
