The x–y plane is the boundary between two transparent media. Medium 1, with z > 0, has a refractive index √2 and medium 2, with z < 0, has a refractive index √3 . A ray of light, incident in medium 1, given by
A = 6√3\(\hat{i}\) + 8√\(\hat{j}\) - 10\(\hat{k}\)
is incident on the plane of seperation. Its angle of incidence (i) and the angle of refraction (r), would be
(1) i = 45° ; r = 60°
(2) i = 45° ; r = 60°
(3) i = 75° ; r = 60°
(4) i = 45° ; r = 55°
