Answer:
They would be shaped like a hill.
Explanation:
A longitudinal wave with higher energy have greater amplitude. Amplitude is the distance between the crust and trough of the wave. Crust is the upper part of the wave while trough is the lower part of the wave. If the distance between crust and trough of the wave is higher so the amplitude is also greater and we can say that the wave contains high amount of energy and vice versa. The shape of the wave just like a hill.
