The maximum kinetic energy of the emitted photoelectrons in photoelectric effects is independent of:

Options

  1. AFrequency of incident radiation
  2. BWavelength of incident radiation
  3. CWork function of material
  4. DIntensity of incident radiation

Correct answer

D. Intensity of incident radiation

Step-by-step solution

By photoelectric equation KEmax⁡=hf−ϕ0KEmax⁡=hcλ−hcλ0\begin{aligned} & \mathrm{KE}_{\max }=h f-\phi_0 \\ & \mathrm{KE}_{\max }=\frac{h c}{\lambda}-\frac{h c}{\lambda_0}\end{aligned}\mathrm{KE}_{\max }$ is independent of intensity of incident radiation.
