When a person walks into the water at the beach, it appears that their feet are separated from their legs. This occurs because the light waves bend as they pass between air and the water. This is an example of

• reflection of light

• absorption of light

• transmission of light

• refraction of light

Why does the arrow appear to change direction as water is poured into the glass? You can try this experiment at home.

• Light waves are bouncing as they pass through air, glass and water.

• Light waves are traveling in a straight line as they pass through air, glass, and water.

• Light waves are not passing through the air, glass, and water.

• Light waves are bending as they pass through the air, glass, and water.

How do waves behave since we can see through jellyfish?

• light waves are striking the jellyfish and bouncing off of it.

• light waves are striking the jellyfish and going into it without passing all the way way through.

• light waves are striking the jellyfish and going all the way through it.

• light waves are striking the jellyfish and being bent.

This is a real picture of a polar taken at a zoo. Fortunately for the polar bear, its head is actually connected to its body. Why does it look like the head is separate from the body?

• Light waves are bouncing as they pass from air to water.

• Light waves are not passing from the air to the water.

• Light waves are traveling in a straight line as they pass from air to water.

• Light waves are bending as they pass from air to water.

Most rooms have hard flat walls. However, music studios have soft, foam-like material on them. Studios use these materials to prevent...

• sound waves hitting the walls from bouncing back.

• sound waves hitting the wall from staying in the walls.

• sound waves hitting the wall from passing all the way through them.

• sound waves hitting the wall from bending.

Why does the dog think he is looking at another dog?

• Light waves are striking the mirror and bouncing off of it.

• Light waves are striking the mirror and going straight through it.

• Light waves are striking the mirror and going into it without going out the other side.

• Light waves are striking the mirror and being bent as they go through it.
