Answer: The frequency of a wave will increase.
Step-by-step explanation:
The relation between the energy and the frequency is as follows;

Here, h is the planck's constant and
is the frequency of the wave.
The energy of the wave is directly proportional to the frequency of the wave. The frequency is inversely proportional to the wavelength. If the energy of the wave increases then the wavelength of the wave decreases.
If the energy of the wave increases then the frequency of the wave will increase.
