You want to construct a photocell that works with a visible light. Three materials are readily available: aluminum (W0 = 4.28 eV), lead (W0 = 4.25 eV), and cesium (W0 = 2.14 eV). Which material(s) would be suitable?
A light source is used in a photoelectric experiment. The metal copper is illuminated,
if a stopping potential of 1.03 V is required, what is the energy of the light shining on
the metal in eV?

our Answer:
b) 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 (2 = 546.1 nm) is
used, a stopping potential of 0.376 V reduces the photocurrent to zero. Based on this
measurement,
