A light ray is incident on a glass slab, it is partially reflected and partially transmitted. Then the reflected ray is

A light is incident on a refractive medium. The light is partially reflected and partially refracted. If both the reflected and refracted rays are mutually perpendicular, then determine the angle of refraction. Refractive index of medium is 1.47.

A wave pulse, travelling on a two piece string, gets partially reflected and partially transmitted at the junction. The reflected wave is inverted in shape as compared to the incident one. If the incident wave has wavelength lambda and the transmitted wave lambda' .

Statement I: A light ray is incident on a glass slab. Some portion of it is reflected and some is refracted. Refracted and reflected rays are always perpendicular to each other. Statement II: Angle of incidence is equal to angle of reflection.

Statement I: A lighr ray is incident on a glass slab. Some portion of it is reflected and some is refracted. Reeefracted and reflected rays are always perpendicular to each other. Statement II: Angle of incidence is equal to angle of reflection.

When light rays are incident on a thick transparent slab then these rays are partly reflected and partly refracted into the slab. At a certain angle of incidence theta , it is found that reflected and refracted rays are mutually perpendicular. What is refractive index of material ?

When a light ray in air is incident on glass at 57^(@) , the reflected ray is completely polarised. If the same ray is incident on water at an angle theta , also the reflected ray is completely polarised. Then
