Question 15 (1 point) A power density of 50 W/cm2 can be absorbed by the rods and the cones found in the retina. Beyond this power density, thermal damage starts occurring in the retina. A dye laser is tuned at 1 = 471 nm and is impinging on the cornea and is then focused on the retina. The focusing system of the eye has a focal length of about f= 20 mm. Find the power density on the cornea of the eye. W, near the eye is 1 mm and the laser power is 5 mW. O 1.59 x 10-3 W/cm2 O 1.59 W/cm2 O 159 W/cm2 O 0.159 W/cm2 None of the other answers
