Answer 1

Stopping potential is defined as the potential required to stop ejection of electron from a metal surface when incident beam of energy greater than the work potential of metal is directed on it.

Answer 2

Stopping potential is defined as the potential required to stop ejection of electron from a metal surface when incident beam of energy greater than the work potential of metal is directed on it.

Define stopping potential (cut-off potential) with reference to photoelectric effect.

Stopping potential is defined as the potential required to stop ejection of electron from a metal surface when incident beam of energy greater than the work potential of metal is directed on it.

In a photoelectric experiment the stopping potential for the photoelectron is 2V for the incidence of wavelength 400 nm. If the incidence the light is changed to 300 nm, the cut of the potential is

Define the term 'stopping potential' in relation to photoelectric effect.

When stopping potential is applied in an experiment on photoelectric effect, no photocurrent is observed. This means that
