Phоtоrefrаctive kerаtectоmy (PRK) is а surgery process that can correct near- and far-sightedness by using a laser to remove part of the lens of the eye to change its curvature and hence focal length. The procedure can remove layers 0.25 m thick using laser pulses lasting 0.012 ps with a beam of wavelength 193 nm. a. (8points) In what part of the electromagnetic spectrum does this laser lie, and what is the energy of each photon? b. (6 points) What is the uncertainty in the energies of the photons?
