CBSE Class 12-science Answered
Ultraviolet light of wavelength 2271 Å from a 100 W mercury source irradiates a photocell made of molybdenum metal. If the stopping potential is -1.3 V, estimate the work function of the metal. How would the photocell respond to a high intensity (~ 105 Wm-2) red light of wavelength 6328 Å produced by a He-Ne laser ?
(Given: h = 6.63 x 10-34 Js, c = 3 x 108 m/s)
