Question:

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.

a. There are 9.7 × 10¹⁴ photons in each pulse. What is the wavelength of the laser?

b. Each pulse lasts a mere 20 ns. What is the average power delivered to the cornea during a pulse?
