The relation between the refractive index and the critical angle of a medium is

A ray of light travels from a medium of refractive index n_(1) to a medium of refractive index n_(2) . If angle of incidence is i and angle of refraction is r, than (sin i)/(sin r) is equal to

A ray of light passes from free space to a medium of refractive index 1.6. If the angle of refraction is half the angle of incidence, the angle of incidence is equal to

The speed of light in a medium is high if the refractive index of the medium is ……. .

When a ray of light passes from air medium to denser medium then the refractive index is
