In a photoelectric experiment to determine the work function for a particular metal surface, two different light sources are used. When blue light (1= 424 nm) is used, a stopping potential of 2.05 V reduces the 14 photocurrent to zero. a) Based on this measurement, what is the work function for this metal? b) What stopping potential would be observed when using the red light?
