A drawing. Short description, A drawing.,Long description, The drawing shows a wave of water moving to the right in a container. As the wave moves, the distance between the peak and trough of the wave gets shorter, but the distance between the peaks of the waves remains the same.
Question
What does the drawing show about the energy of the wave as it moves?
Answer options with 4 options
A.
The energy of the wave increases as shown by the increasing frequency.
B.
The energy of the wave decreases as shown by the decreasing amplitude.
C.
The energy of the wave remains the same as shown by the same wavelength.
D.
The energy of the wave regularly increases and decreases as shown by the peaks and troughs.

the picture is this:
