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 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 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

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 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?

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?

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 :
