Light Review

What is most likely to be true about the temperatures?

• Both setups will have the same temperature. Both are covered with black paper.

• Both setups will have the same temperature. In each setup, the flashlight is the same distance from the paper.

• Setup 1 will have a higher temperature. The flashlight is closer to the ground.

• Setup 2 will have a higher temperature. The angle of the light is closer to 90° with respect to the paper.

A pencil is placed in a glass filled with water. The pencil looks as if it is broken as shown in the picture.

What best explains what you see?

• The light creates a shadow as it moves from the water to the air.

• The direction of the light changes (refracts) as it moves from the water to the air.

• The light bounces back (reflects) as it moves from the water to the air.

• The light shifts over (breaks into two pieces) as it moves from the water to the air.
