A light way deviates by `30^(@)` (which is one third of the angle of incidence) when it gets refrached from vacumm to a medium. Find the rerfraticve index of the medium.

A light way deviates by 30^(@) (which is one third of the angle of incidence) when it gets refracted from vacumm to a medium. Find the refractive index of the medium.

A ray of light is incident at an angle of incidence 45^@ on an equilateral prism and emerge at an angle 45^@ then the refractive index of the medium of the prism is:

A ray of light from a rarer medium strikes a denser medium at angle of incidence 60°. The reflected and refracted rays are perpendicular to each other. The refractive index of denser medium and angle of deviation respectively are

A ray of light is going from rarer to denser medium so that when angle of incidence is 60^(@) reflected and refracted rays are perpendicular to each other.The refractive index of denser medium w.r.t.rarer medium is

A ray of light travelling from first medium is incident at an angle of 30^(@) on the second medium and refracted at an angle of 45^(@) . Find refractive index of the second medium with respect to first medium and angle of emergence.
