Does the 'stopping potential' in photoelectric emission depend upon (i) the intensity of the incident radiation in a photocell? (ii) the frequency of the incident radiation?

What is meant by stopping potential in photoelectric emission ? Does the stopping potential depend on (i) the intensity and (ii) the frequency of the incident light ? Explain

If the stopping potential for photoelectric emission is 0.75 V, the kinetic energy of the fastest photoelectrons is

What is meant by stopping potential in photoelectric emission? Does the stppping potential depend on the intensity and the frequency of the incident light? Explain.

Give reason for maximum kinetic energy of the photoelectrons is independent of the intensity of incident radiation.

How does (i) photoelectric current and (ii) kineic energy of the photoelectrons emitted in a photocell vary if the intensity of the incident radiation is doubled?

Explain the effect of increase of (i) frequency (ii) intensity of the incident radiation on photoelectrons emitted by a phototube.

How does the kinetic energy of photoelectrons change due to increase in intensity of incident light?

If in a photo-electric experiment, the wavelength of incident radiation is reduced from 6000 Å " to " 4000 Å then

Explain giving reasons for the following: Photoelectric current in a photocell increase with the increase in the intensity of the incident radiation.

Statement I: The stopping potential becomes double when the frequency of the incident radiation is doubled Statement II: Work function of the metal and the threshold frequency of photoelectric effect are proportional to each other.
