Homework Answers
The energy of a photon is proportional to its frequency. When a photon is bounced from an electron, its energy is decreased. That is, the frequency also decreased.
Frequency is inversly proportional to the wavelength of photon. When frequency decreases, wavelength increases. Therefore, in this case, the wavelength increases.
Hence option d is the right answer.
