Question

A deep-sea diver points a laser that emits unpolarized light throught water and hopes to have that the light will pass through 2 polarized sheets abocve the water. The index of refraction of the water is 1.33 and the index of refraction is 1.0 for air.

A. If the polarizing sheets are positioned at an angle of 30 degrees above the water's surface, at what angle from the normal should the laser (incident light) positioned?

B. What is the angle of the reflected light?

C. The differnce in polarizing angles of the polarizing sheets is 60 Degrees. What percentage of the light that leaves the water is transmitted by the polarized sheets?

D. What would the critical angle equal if the diver wishes to have no light leave the water
