A photon of wavelength 200 nm is scattered by an electron that is initially at rest.Which one of the following statements concerning the wavelength of the scattered photon is true?
A)The wavelength is zero nm.
B)The wavelength is 200 nm.
C)The wavelength is 100 nm.
D)The wavelength is greater than 200 nm.
E)The wavelength is less than 200 nm,but greater than zero.

Quizplus · Accepted Answer

When a photon is scattered by an electron (Compton scattering), the wavelength of the scattered photon increases due to the transfer of energy from the photon to the electron. This means the scattered photon's wavelength is greater than the original wavelength.
