Question

A research ship in the Pacific Ocean is testing a new method of detecting pollutants in ocean water (nw 1.3330). Their experimental apparatus includes two lasers which hang over the side of the ship and point downward into the water (the lasers themselves are suspended in the air above the surface of the ocean). One laser is violet (A 400 nm, a20 0.0044 m1) and the other is red (A 700 nm, a20 0.6 m1). Both lasers are very bright, with an intensity of 4500 w/m2 What is the fraction of light coming from the red laser beam that is transmitted from the air into the water? Submit Answer Tries o/12 What is the intensity of the blue laser beam at a depth of 1 m? Submit Answer Tries 0/12 What is the intensity of the red laser beam at a depth of 1 m? Submit Answer Tries 0/12
