Energy and Power of a Wave: Frequency Dependence

WAVES-BFHB9L

Two mechanical waves are mostly identical (have the same amplitude, velocity, and are traveling through the same medium), except that one wave has a longer wavelength than the other.

Which wave transmits the greatest power?

A

The one with the longer wavelength.

B

The one with the shorter wavelength.

C

They both have exactly the same power.

D

It depends on whether they are transverse or longitudinal waves.
