If the frequency of incident radiation on a photocell is doubled for the same intensity, what changes will you observe in (i) kinetic energy of photoelectrons emitted (ii) photoelectric current?

If the frequency of incident radiation on a photocell is doubled for the same intensity, what change will you observe in the kinetic energy of emitted photoelectrons ?

In photoelectric effect if the intensity of light is doubled then maximum kinetic energy of photoelectrons will become

If the frequency of incident light falling on a photosensitive metal is doubled, the kinetic energy of the emitted photoelectron is

If the intensity of radiation incident on a photocell be increased four times, then the number of photoelectrons and the energy of photoelectrons emitted respectively become.

If the intensity of radiation incident on a photocell be increased four times, then the number of photoelectrons and the energy of photoelectrons emitted respectively become.

Explain giving reasons for the following : (a) Photoelectric current in a photocell increases with the increase in intensity of the incident radiation. (b) The stopping potential V_0 varies linearly with the frequency nu of the incident radiation for a given photosensitive surface with the slope remaining the same for different surfaces. (c) Maximum kinetic energy of the photoelectrons is independent of the intensity of incident radiation.
