Wave Behavior Review

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.

Why is it a good idea to wear dark colors in the winter and not the summer?

• Light waves are striking the dark material and bouncing off of it. Energy from the wave gets converted to thermal energy.

• Light waves are striking dark material and going through it. Energy from the wave gets converted to thermal energy

• Light waves are striking the dark material and being absorbed. Energy from the wave gets converted to thermal energy.

• Light waves are striking the dark material and being bent as they pass through. Energy from the wave gets converted to thermal energy.

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. (reflecting)

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

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

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

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. (reflecting)

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

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

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

Sunglasses lenses are normally darker colored so they can __________ light getting to your eyes, but it is also important they can ___________ light since you need to see through them.

• absorb; transmit

• refract; diffract

• reflect; transmit

• diffract; absorb
