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 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 ?

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

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 :

Find the angle of refraction for a ray of light falling on a transparent medium of refractive index 1.6. The reflected and refracted rays are perpendicular to each other.

A ray of light from a denser medium strikes a rarer medium at an angle of incidenc i. The reflected and refracted rays make an angle of pi//2 with each other. If the angles of reflection and refraction are r and r^(') , then the criticall angle will be
