Sound Waves Energy Quiz

Based on the provided graphs, which statement best explains which animal's sound waves has more total energy?

• A lion’s roar because it has a higher amplitude.

• A lion’s roar because it has a higher frequency.

• A mouse’s squeak because it has a higher amplitude.

• A mouse’s squeak because it has a higher frequency.

Based on the provided graphs, what are the unit rates for E:A² for each animal’s sound waves?

• Lion roar unit rate = 1/2; Mouse squeak unit rate = 2

• Lion roar unit rate = 2; Mouse squeak unit rate = 1/2

• Lion roar unit rate = 1/2; Mouse squeak unit rate = 1/2

• Lion roar unit rate = 2; Mouse squeak unit rate = 2

The student is also interested in looking at the energy of sound waves from other animals. For example, the sound waves from a screaming monkey have both high amplitude and high frequency. Which of the following graphs most likely represents the sound waves from a screaming monkey?

• Graph A

• Graph B

• Graph C

• Graph D

A wave that carries more energy has ______ than a wave that carries less energy.

• a bigger amplitude

• a smaller amplitude

• the same amplitude

• a lower frequency

If the input of energy was the same, how would you expect a thick metal spring to behave differently from a thin metal spring?

• The thick spring would have a larger amplitude.

• The thick spring would have a smaller amplitude.

• The amplitudes in the two springs would be the same.

• The amplitudes would start off the same but gradually become different.
