An electron is in the ground state of a square well of width L = 4.00 x 10-10 m. The depth of the well is six times the ground-state energy of an electron in an infinite well of the same width. Part A What is the kinetic energy of this electron after it has absorbed a photon of wavelength 79 nm and moved away from the well? Express your answer in electron volts.
