Two parallel light rays are incident at one surface of a prism of refractive index `1.5`. What is the angle between the rays as they emerge? `sin^-1(0.75)=48.5^@`

A ray of light is incident on the surface of plate of glass of refractive index 1.5 at the polarising angle. The angle of refraction of the ray will be

A ray of light is incident normally on one face of an equilateral prism of refractive index 1.5 . The angle of deviation is: (Given sin^-1.(2)/(3)=42^@ )

A ray of light is incident normally on one face of an equilateral prism of refractive index 1.5 . The angle of deviation is: (Given sin^-1.(2)/(3)=42^@ )

A ray of light enters a rectangular glass block and is incident on the lower face of the block. Angle of incidence is 30^(@) . Part of the ray is reflected inside it and the rest emerges out of the block. Refractive index of glass is 1.5. What is the angle between the emergent ray and the reflected ray? [sin 48^(@) = 0.75]

If a light ray incidents normally on one of the faces of the prism of refractive index 2 and the emergent ray just grazes the second face of the prism, then the angle of deviation is
