State the influence of work function on kinetic energy of electrons emitted in a photocell. If the intensity of the incident radiation is doubled, what changes occur in the stopping potential and photoelectric current?

State the dependence of work function on kinetic energy of electrons emitted in a photocell. If the intensity of the incident radiation is doubled, what changes occur in the stopping potential and photoelectric current?

if the maximum k.E. of electrons emitted by a photocell is 4 eV, what is the stopping potential?

Sketch a graph between frequency of incident radiations and stopping potential for a given photosensitive material. What information can be obtained from the value of the intercept of potential axis? A source of light of frequency of greater than the threshold freuency is placed at a distance of 1 m from the cathode of a photocell? the distnace of hte light sources from the cathode is reduced explain giving reasons, what change will you observe in the Stopping potential.

Draw a graph showing the variation of stopping potential with frequency of incident raditions in relation to photoelectric effect. Deduce an expression for the slope of this graph using Einstein's photoelectric equation.
