In the Compton effect,a photon of wavelength and frequency f hits an electron that is initially at rest.Which one of the following occurs as a result of the collision?
A)The photon is absorbed completely.
B)The photon gains energy,so the final photon has a frequency greater than f.
C)The photon gains energy,so the final photon has a wavelength greater than .
D)The photon loses energy,so the final photon has a frequency less than f.
E)The photon loses energy,so the final photon has a wavelength less than.

In the Compton effect, a photon collides with a stationary electron and transfers some of its energy to the electron, causing the photon's frequency to decrease (losing energy) and its wavelength to increase (wavelength increases as frequency decreases). Therefore, the final photon has a frequency less than f, and its wavelength will also be greater than the original 11ec9e00_fe61_49c7_8d20_b73bf57c2b5e_TB6393_11. Choice D is the only option that reflects these changes.
