Laser coagulation surgery is used to treat a number of eye diseases, such as age-related macular degeneration and diabetic retinopathy. during the procedure, an argon laser (with principal wavelengths of 514 nm and 488 nm) is used to cauterize ocular blood vessels. the laser light absorbed by the tissue raises its temperature until proteins become coagulated. for the purposes of the following questions, use c = 3.00×108 m/sand h = 4.14×10−15 ev⋅s.

what is the photon energy of the 514 photon?
