Light of constant intensity but varying wavelength was used to illuminate the cathode in a photoelectriceffect experiment. The graph shows how the stopping potential depended on the frequency of the light. What is the work function, in eV, of the cathode?

When ultraviolet light with a wavelength of 351 nm falls on a certain metal surface, the maximum kinetic energy of the emitted photoelectrons is measured to be 1.76x10-19 J. How much energy, in Joule, does an electron have to gain in order to escape from the metal surface? Exponential format with 3 SF.
