Question 1

Identify the properties of transverse and longitudinal waves. Amplitude: Compression: Frequency: Period: Wavelength:

Revolt · Accepted Answer

C: both longitudinal and transverse

Question 2

Which wave, A or B, has lower energy?

Revolt · Accepted Answer

C: A, because it has a lower amplitude

Question 3

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?

Revolt · Accepted Answer

Tara's graphical representation is incorrect. The relationship between the amplitude of a wave and its energy is not linear; instead, the energy of a wave is proportional to the square of its amplitude (E ∝ A²). Therefore, her graph should show an exponential or parabolic curve rather than a straight line to accurately represent how energy increases as amplitude increases.

Question 4

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

Revolt · Accepted Answer

A: As the amplitude of a wave increases, the energy it carries also increases.; B: The graph shows that as the amplitude of a wave increases, the energy it carries decreases.; C: The graph shown does not correctly represent the relationship between amplitude and energy.
