Homework Statement
In perspective to the photoelectric effect I found following question:
Electric current is charge flowing per unit of time. If we increase the kinetic energy of the photoelecrons (by increasing the energy of the incident photons), shouldn’t the current increase, because the charge flows more rapidly? Why doesn’t it?
Homework Equations
E_kin = h*f - φ
φ: work function
The Attempt at a Solution
Maybe if I increase the energy of the photons, the same number of electrons are emitted in the same unit of time but with greater kinetic energy and therefore there is a greater difference between the separate electrons getting emitted? But I have no idea why this should occur ( there should be the same number of photons in a lighthbeam which could knock out electrons).
