Tara prepared a report to show how the amplitude of waves affects the energy of waves. Is her graphical representation correct? Why or why not?

Answer:

No. The graph is incorrect because it shows energy decreasing as amplitude increases, but a wave’s energy increases as its amplitude increases.

Does sound travel faster in a warm room or a cold room? Explain your answer.

Answer:

Sound travels faster in a warm room because temperature affects the velocity of a wave. In a warm room, the particles of air move faster and have higher chances of bumping into each other, which then increases the instances of energy transfer.

What did you include in your response? Check all that apply.

A
Sound travels faster in a warm room.
B
The temperature of a medium affects the velocity of a wave.
C
The higher the temperature, the more bumping between the particles of the medium and the more instances of energy transfer.
