Photorefractive keratectomy (PRK) is a laser-based surgical procedure that
corrects near- and farsightedness by removing part of the lens of the eye to
change its curvature and hence focal length. This procedure can remove layers

A sample of hydrogen atoms is irradiated with light with wavelength 85.5 nm, and electrons are observed leaving the gas. (a) If each hydrogen atom were initially in its ground level, what would be the maximum kinetic energy in electron volts of these photoelectrons? (b) A few electrons are detected with energies as much as 10.2 eV greater than the maximum kinetic energy calculated in part (a). How can this be?
An electron beam and a photon beam pass through identical slits. On a distant
screen, the first dark fringe occurs at the same angle for both of the beams.
The electron speeds are much slower than that of light. (a) Express the energy
of a photon in terms of the kinetic energy
A certain atom has an energy level 2.58 eV above the ground level. Once
excited to this level, the atom remains in this level for 1.64
