A parallel beam of light falls normally on the first face of a prism of small angle .At the second face it is partly reflected,the reflected beam striking at the first face again, and emerging from it in a direction making an angle `6^(@)` 30' with the reversed direction of the incident beam. The refracted beam is found to have undergone a deviation of `1^@ 15'` from the original direction.Find the refractive index of the glass and the angle of the prism.

A parallel beam of light falls normally on the first face of a prism of small anlge A. At the second face it is partly transmitted partly reflected. The reflected beam striking the first face again, emerges out through the first face at an angle of 6^(@)30' with the normal to the first face. The refracted beam is found to hae undergone a deviation of 1^(@)15' from the original direction. Calculate the refractive index and angle of the glass prism .

A parallel beam of light falls normally on the first face of a prism of small refracting angle. At the second refracting face it is partly reflected and partly transmitted. The reflected light strikes the first face again and emerges from it making an angle of 4° with the reversed direction of incident beam. The deviation suffered by refracted ray is 1° from original direction of incident ray. Find the refractive index of glass of the prism and the angle of the prism.

A paralles beam of white light falls on one face of a prism. The light emerging from the other face suffers-

A monochromatic ray of light in incident normally on a refracting face of a prism of angle 30^(@) . The refractive index of the material of the prism 1.5 . The angle of emergence will be

A parallel beam of light is incident on a prism as shown in figure. Such that the rays get reflected from opposite faces. The angle of deviation delta between reflected rays from faces AB and AC is-
