Wave Calculations Practice

What does energy have to do with wavelength and frequency?

• The higher the frequency the less energy the wave has.

• The lower the frequency the more energy the wave has.

• The shorter the wavelength the more energy the wave has.

• The longer the wavelength the more energy the wave has.
