Very short pulses of high-intensity laserbeams are used to repair detached portions of the retina of the eye. Thebrief pulses of energy absorbed by the retina weld the detached portionsback into place. In one such procedure, a laser beam has a wavelengthof 810 nm and delivers 250 mW of power spread over a circularspot 510 mm in diameter. The vitreous humor (the transparent fluid thatfills most of the eye) has an index of refraction of 1.34. What are the wavelength and frequency of the laser lightinside the vitreous humor of the eye?
