An electron has a kinetic energy of 12.3 ev . The electron is incident upon a rectangular barrier of height 19.0 ev and width 1.00 nm . If the electron absorbed all the energy of a photo of green light ( with wavelength 546 nm ) at the instant it reached the barrier , by what factor would the electron's probability of tunneling through the barrier increase ? photon

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER An electron has a kinetic energy of 12:3 ev. The electron is incident upon a rectangular barrier of height 10.0 ov and width 1 00 nm. If the election absorbed all the energy of a photon of green right (with wavelength 546 mm) at the instant if reached the barrier by what factor would the olactron's probabilty of tunneling through the barrier Increase? how much energy does the photon carry?
