The wavelength is related to frequency by. nu = c / lambda. where c is the speed of light and lambda is the wavelength. So you could also write. E = h c / lambda.
The apparent change in frequency between the source of a wave and the receiver of the wave is because of relative motion between the source and the receiver. To understand the Doppler effect, first assume that the frequency of a sound from a source is held constant. The wavelength of the sound will also remain constant.

The speed stays the same. The frequency is independent of the speed. What happens to the wavelength if you cut the frequency in half? How do you know? The wavelength doubles. Since they are inversely proportional, if the frequency is cut in half,' the wavelength doubles. (2 is the inverse of 1/2) 13.
