When light with a wavelength 480 nm or shorter shines on a metal surface, a current is measured.

A. What is the work function of this metal?

B. What is the maximum kinetic energy an electron will have if violet light (380 nm) shines on the surface?

C. How fast would those electrons be moving with that kind of energy?

D. How large a battery (in volts) would be necessary to stop the electrons from flowing in the circuit?
