Homework Statement


If X represents the intensity of monochromatic blue light and Y represents the energy of each photon of the light, which one is the correct graph below?

Homework Equations


KE=hƒ-∅, where ∅ is the work function
Energy of a photon= hƒ

The Attempt at a Solution


Increasing the intensity of light does not increase the energy of the photon. However, It does increase the number of photons, which increases the number of ejected electrons (more current). Does that mean the graph is the one with consistent energy in E.

Since "Y represents the energy of each photon of the light," the photoelectrons have nothing to do with the question. The answer is indeed E.

I don’t know why the answer key says it is C, so I had to check on my understanding.
