Waves and Wave Behavior

How does this affect a sound wave? A light wave?

• Decreased amplitude of the light wave means dimmer light

• Increased amplitude of the sound wave means louder sound

• Increased amplitude of the light wave means brighter light

• Decreased amplitude of the sound wave means softer sound

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.

• 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.
