Ultraviolet light of wavelength 2271 from a 100 W mercury source irradiates a photo- cell made of molybdenum metal. If the stopping potential is -1.3 V, estimate the work function of the metal. How would the photo-cell respond to a high intensity (~10 W m) red light of wavelength 6328 produced by a He-Ne laser?
