the maximum kinetic energy of a photoelectron, Ek,max , to the smallest amount of energy, E0, needed to free an electron from the metal, and the energy, Eph , of the incident photons of light:

Ek,max = Eph – E0

In addition, you know from Equation 10.1 that Eph = hf where h is the Planck constant and f is the frequency of the incident light.

Which one of the following graphs represents the relationship between Ek,max and f ?

attachment of graphs is attached.

thanks trigger.
