Increase in the frequency of the incident radiations increases the

If the intensity of the incident radiation in a photocell is increased, how does the stopping potential very?

Assertion (A) : On increasing the frequency of light larger number of photoelectrons are emitted . Reason (R) : The number of electrons emitted depends on the intensity of incident light.

Explain photoelectric effect Explain the effect of increase of intensity of incident radiations on photoelectrons emitted by a photo-tube.

An increase in the frequency of the incident light increase the velocity with which photoelectron is ejected. Explain how?

Assertion(A): The kinetic of the photo electron ejected increases with increases in intensity of incident light. Reason(R): Increase in intensity of incident light increases the rate of emission.

Assertion : The increase in intensity of incidence light decreases the kinetic energy of emitted electrons. Reason : When frequency of light increases , the intensity of light increases.

Of the following statement about the photoelectric effect, which are true and which are false? (a) The greater the frequency of the incident light is, the greater is the stopping potential. (b) The greater the intensity of the incident light is, the greater is the cutoff frequency. (c) The greater the work function of the target material is, the greater is the stopping potential. (d) The greater the work function of the target material is, the greater is the cutoff frequency. (e) The greater the frequency of the incident light is, the greater is the maximum kinetic energy of the ejected electrons. (f) The greater the energy of the photons is, the smaller is the stopping potential.

How does kinetic energy of ejected photoelectrons depend upon the frequency of incident radiation?
