In LASIK surgery, a laser is used to reshape the cornea of the eye to improve vision. The laser produces extremely short pulses of light, each containing 1.0 mJ of energy. in each pulse, there are 9.7×1014 photons.

(a) What is the wavelength of the laser?

(b) Each pulse lasts only 20 ns. What is the average power delivered to the eye during a pulse?
