A thick sheet of plastic, ( n = 1.950), is used as the side of an aquarium tank. Light reflected from a fish in the water has an angle of incidence of 35.3°. At what angle does the light enter the air?_____I know how to do this problem, use Snell's lawn1sintheta1 = n2sintheta2However, I get arcsintheta = 1.1268223675478354227336839549523, which isn't possible.Thanks guys for the help!
sintheta1=1/1.95sin35.3° theta1=17.2377°
