Wave Behaviors 1

In class we will explore how light and sound waves interact with various materials. Depending on the material waves can bounce off the material, go into the material, pass through the material in a straight line, or pass through the material in a bent line.

• I don't get it.

• GOT IT!

We can see through jellyfish because...

• 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.

Listen to the recording of someone yelling in a tunnel. Why do we hear something after each yell?

• Sound waves are striking the walls of the tunnel and bouncing off of the walls.

• Sound waves are striking the walls of the tunnel and going into the walls (they are not passing all the way through).

• Sound waves are striking the walls of the tunnel and going all the way through the walls.

• Sound waves are striking the walls of the tunnel and being bent as they go through the walls.

This is a real unedited photo taken with a cell phone. The man is in a swimming pool with glass walls and water filled to the top. Why does it look like his head is separate from his 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 the dark material and staying in 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 bent as they pass through. Energy from the wave gets converted to thermal energy.

It probably would not be a good idea to put a music studio in your bedroom without sound proofing first because...

• sound waves would strike the walls and then bounce off of the walls.

• sound waves would strike the walls and then stay in the walls.

• sound waves would strike the walls and then go through the walls

• sound waves would strike the walls and then bend.

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 into it without going out the other side.

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

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

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 not passing through the air, glass, and water.

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

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

People often put noise-cancelling earmuffs on babies when they bring them to loud places. This is to help protect their ears. How do you think this works? Select TWO answers.

• Sound waves are striking the earmuffs and bouncing off of them.

• Sound waves are striking the earmuffs, going into them, but not passing through them.

• Sound waves are striking earmuffs and going through them.

• Sound waves are striking the earmuffs and being bent as they pass through.
