A ray of light is incident at an angle `i` from denser to rare medium. The reflected and the refracted rays are mutually perpendicular. The angle of reflection and the angle of refraction are respectively r and r'. Then the critical angle will be:

A ray of light passes from a denser medium to a rarer medium at an angle of incidence i. The reflected and refracted rays make an angle of 90^@ with each other. The angle of reflection and refraction are resepectively r and r'. The critical angle is given by :

A ray incident from denser medium to rarer medium. If angle between reflected ray and refracted ray is 90^0 then angle angle of reflection r and angle of refraction r' will be respectively.
