Stopping potential for photoelectrons: |
does not depend on the frequency of the incident light does not depend on the nature of the material of cathode depends on both the frequency of the incident light and the nature of the material of cathode depends on the intensity of the incident light |
depends on both the frequency of the incident light and the nature of the material of cathode |
The correct answer is Option (3) → depends on both the frequency of the incident light and the nature of the material of cathode $eV_s=hv-\phi$ [Photoelectric equation] where, $v$ - frequency of the incident light $\phi$ = work function (material property) $v_s$ = Stopping potential ∴ $v_s$ depends upon both frequency (v) and nature of the material ($\phi$). |
