In the Compton effect,a photon of wavelength $\lambda$ and frequency f is scattered from an electron.Initially,at rest
A) the electron gains energy from the photon so that the scattered photon's wave length is less than $\lambda$.
B) the electron gives energy to the scattered photon so the photon's frequency is greater than f.
C) momentum is not conserved,but energy is conserved.
D) the photon loses energy so that the scattered photon has a frequency less than f.

In the Compton effect, the photon loses energy while scattering from an electron. This causes the frequency of the scattered photon to be less than the initial frequency (f). Therefore the wavelength of the scattered photon will be greater than the initial wavelength (λ). This is due to the conservation of both energy and momentum in the interaction. So, option D is correct as the photon loses energy to the electron.
