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

The maximum kinetic energy of the emitted photoelectrons in photoelectric effects is independent of:
  1. Frequency of incident radiation
  2. Wavelength of incident radiation
  3. Work function of material
  4. Intensity of incident radiation

Solution

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