What stopping potential would be observed

Reference no: EM13273420

Two light sources are used in a photoelectric experiment to determine the work function for a particular metal surface. When green light from a mercury lamp (lambda = 546.1 nm) is used, a stopping potential of 0.850 V reduces the photocurrent to zero.

(a) Based on this measurement, what is the work function for this metal? eV

(b) What stopping potential would be observed when using light from a red lamp (lambda= 671.0 nm)? V
