In Einstein's photoelectric experiment, the kinetic energy (K.E.) of an electron displaced from a metal by a photon was the difference in energy between the photon and a threshold energy value for the metal. If you were to perform a similar experiment with the metal platinum, which has a threshold energy of 9.04 x 10-19 J, and ultraviolet light of wavelength 45.5 nm, what would be the speed (v) of the dislodged electron in meters per second? (K.E. = 1/2mv². The mass of the electron = 9.109 × 10-³1 kg.)

Question 8 of 24
In Einstein's photoelectric experiment, the kinetic energy (K.E.) of an
electron displaced from a metal by a photon was the difference in
energy between the photon and a threshold energy value for the
metal.
If you were to perform a similar experiment with the metal platinum,
which has a threshold energy of 9.04 x 10-1⁹ J, and ultraviolet light of
wavelength 45.5 nm, what would be the speed (v) of the dislodged
electron in meters per second? (K.E. = 1/2mv². The mass of the
electron = 9.109 × 10-31 kg.)
