In a historical experiment to determine Planck's constant, a metal surface was irradiated with light of different wavelengths. The emitted photoelectron energies were measured by applying a stopping potential. The relevant data for the wavelength `(lambda)`. ) of incident light and the corresponding stopping potential `(V_0 )` are given below :
