Question

# The factors on which the rate of emission depends arei) the material of the surface ii) colour of the surface iii) area of the surfacei) the material of the surface ii) colour of the surface iii) volume of the surfacei) the roughness of the surface ii) temperature of the surface iii) area of the surfacei) the material of the surface ii) temperature of the surface iii) area of the surfacei) the roughness of the surface ii) temperature of the surface iii) volume of the surface

Solution

## The correct option is D i) the material of the surface ii) temperature of the surface iii) area of the surfaceThe number of electrons emitted per second i.e. the rate of emission depends upon
