post module assignment Q 19

Postby Eugene Chung 3F » Wed Oct 23, 2019 12:34 am

is the answer D? I feel like A, B, C are right because they explain the main photoelectric effect equation showing conservation of energy

Yes, the answer is D. The first three are all variations of the energy change between a photon and the electron/metal.

D does not represent the photoelectric effect. Instead, the equation shows the inverse relationship of frequency and wavelength.

The answer should be D. None of the other ones is a correct representation of the photoelectric effect.

It's D because even though we use that equation often while trying to solve photoelectric effect-related problems, it is not an equation we use to describe what is going on in the photoelectric effect. D is the equation we use to find either the frequency or wavelength of a photon, as it is the classical mechanics description of light.
