Question: Consider laser eye surgery, in which laser light with a wavelength of 514 nm at a power output of 1.5 W is used to reattach

Consider laser eye surgery, in which laser light with a wavelength of 514 nm at a power output of 1.5 W is used to reattach a detached retina. Suppose the laser is pulsed for 0.050-s time intervals.

(a) During this time, how many photons are emitted by the laser?

(b) What is the difference in energy between the two energy levels involved in this laser transition?
