In photoelectric effect, we assume the photon energy is proportional to its frequency and is completely absorbed by the electrons in the metal. Then the photoelectric current

Options:

Answer:

Solution:

$\dot{N}_{e} = \frac{η P}{h ν} i = e \dot{N}_{e} = \frac{eη P}{h ν}$

Current therefore depends on intensity and frequency in the stated absorption model
