An incident plane wavefront makes angle `53^@` with surface of medium in air. The refracted wavefront makes angle `37^@` with the surface. Refractive index of medium is:
(A) 3/2
(B) 4/3
(C) 3/4
(D) 2/3

Brewster angle for air to water transition is (refractive index of water is 4/3 )

A ray of light incidents on a refracting surface at 30^(@) with the surface . If the angle of refraction is 45^(@) refractive index of the medium is
