Interactions of Light

In the Bending Light Lab, as the angle of incoming light decreases, the percentage of light transmitted through the water ________ and the percentage of light reflected ________.

• decreases, increases

• increases, decreases

In the Bending Light Lab, how does the angle of incoming light compare to the angle of light reflecting off of the surface of the water?

• The angle of the incoming light is the SAME as the angle of light reflecting off the surface of the water.

• The angle of the incoming light is GREATER than the angle of light reflecting off the surface of the water.

• The angle of the incoming light is LESS than the angle of light reflecting off the surface of the water.

In the Bending Light Lab, what happens when light passes through the same medium for both the top and the bottom portions of the simulator window?

• The light bends a lot

• The light bends a little

• The light does not bend or reflect at all

• The light completely reflects

The lab is called "Bending Light" because it shows how light _______ when it passes from medium to another medium.

• bends

• disappears

• reacts

• absorbs

In a vacuum/empty space, the speed of light...

• can vary

• is always 300,000 km/s

• is slower than the speed of light through a medium

• is slow

In what context would would light travel even faster than through air?

• Through vacuum/empty space

• Through glass

• Through water

• Through a solid

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

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

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.
