If a ray of light in a denser medium strikes a rarer medium at an angle of incidence i, the angles of reflection and refraction are respectively, r and r' If the reflected and refraction rays are at right angles to each other, the critical angle for the given pair of media is

A ray of light with wavelength 5000 nm travelling from a medium with refractive index (3/2) suffers partial reflection and refraction in a medium of refractive index (4/3) . Find wavelength of reflected and refracted ray.

A ray of light from a denser medium strikes a rare medium as shown in figure. The reflected and refracted rays make an angle of 90^(@) with each other. The angles of reflection and refraction are r and r'. The critical angle would be

Unpolarized light is incident on a plane glass surface. The angle of incidence so that reflected and refracted rays and perpendicular to each other, then

A light ray suffers reflection and refraction at the boundary in passing from air to water. Draw a neat labelled ray diagram to show it.

In Figure, a ray of light A incident from air suffers partial reflection and refraction at the boundary of water. (a) Complete the diagram showing (i) the reflected ray B and (ii) the refracted ray C. (b) How are the angles of incidence i and refraction r related ?

Unpolarized light is incident on a plane glass surface having refractive index . The angle of incidence at which reflected and refracted rays would become perpendicular to each other is :

Unpolarized light is incident on a plane glass surface. What should be the angle of incidence so that the reflected and refracted rays are perpendicular to eachother ?
