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.

At polarising angle, the angle between reflected and refracted rays is

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:

What is the angle between the reflected and refracted rays at polarizing angle ?

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 :

If the angle between incident ray and reflected ray is 120^(@) , what is the angle of incidence ?

A ray is incident at an angle 40^@ with a mirror. The angle between the normal and reflected ray is

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

The angle between incident ray and reflected ray or refracted ray is called _____

A ray of light from a denser medium strikes a rarer medium at angle of incidence i . The refrected and the refracted rays make an angle of 90^@ with each other. The angles of reflection and refraction are r and r^' respectively. The critical angle is (i) sin^-1(tanr) (ii) sin^-1(tani) (iii) sin^-1(tanr) (iv) tan^-1(tani)
