If the angle of incidence is `0^(@)`, the angle of refraction is `90^(@)`.

Angle of incidence for which the angle of refraction becomes 90^(@)

A ray of light strikes an air-glass interface at an angle of incidence (i=60^@) and gets refracted at an angle of refraction r. On increasing the angle of incidence (i gt 60^@) , the angle of refraction r

For a prism kept in air, it is found that for an angle of incidence 60^(@) , the angle of refraction A, angle of deviation delta and anble of emergence e become equal. Then, the refractive index of the prism is

A ray of light passes from vaccum into a medium of refractive index n. If the angle of incidence is twice the angle of refraction, then the angle of incidence is

A ray of light passes from vacuum into a medium of refractive index n . If the angle of incidence is twice the angle of refraction , then the relation between the angle of incidence and the refractive index is

A ray of light passes from vaccume into a medium of refractive index n. if the angle of incidence is twice the angle of refraction, then the angle of incidence is

A ray of light travels from air to glass . It is found that the angle of refraction is half the angle of incidence . Then the angle of refraction is given by
