A light beam containing a number of wavelengths is used in an photoelectric experiment. The stopping potential :

is related to mean wavelength.

is related to maximum wavelength

is related to the maximum K.E. of emitted photoelectrons

is related to intensity of incident light.

Text Solution

Verified by Experts

Stopping potential is the measurment of maximum kinetic energy of emitted photoelectrons and kinetic energy of emitted photoelectrons is linearly with the frequency of incident light correponding (i,e corresponding to shortest wavelength, K.E is maximum). Stopping potential is independent of intensity
