Webb21 aug. 2024 · I = nhf. In both the equations we see that intensity and frequency are related. But in Einstein's theory both have different results. It is further seen that the individual energy packets ϵ are related to frequency as ϵ = h f. Now, say we have a light source with intensity E = 100 and the work function ϕ 0 = 1. WebbPhotoelectrons are emitted from the metal when the incident light is above a threshold frequency. The kinetic energy of the emitted photoelectrons increases with the frequency of the light. The number of emitted photoelectrons increases with …
