Light from a denser medium 1 passes to a rarer medium 2. When the angle of incidence is `theta` the partially reflected and refracted rays are mutually perpendicular. The critical angle will be

Light from a denser medium I goes to a rarer medium II.When angle of incidence is theta ,the reflected and refraced ray s are perpenciculat to each other .The crtitical angle is:

A ray of light from a denser medium strikes a rarer medium at an angle of incidence i. if the reflected and the refracted rays are mutually perpendicular to each other, what is the value of the critical angle ?

A ray of light enters from a rarer to a denser medium. The angle of incidence is I . Then the reflected and refracted rays are mutually perpendicular to each other . The critical angle for the pair of media is

A ray of light from a denser medium strikes a rarer medium at an angle of incidence i = tan^( -1)(1//2) . If the reflected and the refracted rays are mutually perpendicular to each-other, what is the value of the critical angle in degree?
