A ray of light is travelling from medium ‘A’ into a rarer medium B. The angle of incidence ^siS 45° and the angle of deviation is 15° . The refractive index of medium A w.r.to B is

A ray of light is travelling from medium A to medium B . The refractive index of the medium B does not depend upon

When a ray of monochromatic light enters from rarer medium to denser medium obliquely, the angle of incidence i and angle of refraction r is related as

Light travels from a rarer medium to a denser medium. The angle of incidence and refraction are respectively 45^@ and 30^@ . Calculate the refractive index of the second medium with respect to the first medium.

Light traveling from a transparent medium to air undergoes that internal reflection at an angle of incident of 45^(@) . Then refractive index of the medium may be
