In Einstein's photoelectric experiment, the kinetic energy of an electron displaced from a metal by a photon was the difference between the energy of a photon and a threshold energy value for the metal. If you were to perform a similar experiment with cobalt, which has a threshold energy of 8.01 x 10-¹⁹ J, and ultraviolet light of wavelength 41.3 nm, what would be the kinetic energy (in J) of the electron displaced?

Question
In Einstein's photoelectric experiment, the
kinetic energy of an electron displaced from
a metal by a photon was the difference
between the energy of a photon and a
threshold energy value for the metal. If you
were to perform a similar experiment with
cobalt; which has a threshold energy of 8.01
x 10-1⁹ J, and ultraviolet light of wavelength
41.3 nm, what would be the kinetic energy
(in J) of the electron displaced?
