When the refraction takes place through a glass prism the emergent ray always bends towards the _______ of prism.

When the refraction takes place through an equilateral prism.

In refraction of light through a prism the light ray:

(a) Define the following when refraction takes place through an equilateral glass prism (i) angle of incidence (ii) prism (iii) refracting angle of prism (iv) angle of emergence (v) angle of deviation (b) How are angle of incidence, angle of prism, angle of emergence and angle of deviation related to each other?

Explain the refraction of light through a triangular glass prism using a labelled ray diagram. Hence define the angle of diviation.

A ray of light incident at an angle of incidence 'I' passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its base and emerges from the prism at an angle of emergence 'e'. How is the angle of emergence 'e' related to the angle of incidence 'i' ?

A ray of light incident at an angle of incidence 'I' passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its base and emerges from the prism at an angle of emergence 'e'. What can you say about the value of the angle of deviation in such a situation ?

(a) Deduce the expression, by drawing a suitable ray diagram, for the refractive index of a triangular glass prisms in terms of the angle of minimum deviation (D) and the angle of prism (A). Draw a plot showing the variation of the angle of deviation with the angle of incidence. (b) Calculate the value of the angle of incidence when a ray of light incident on one face of an equilateral glass prism produces the emergent ray, which just grazes along the adjacent face. Refractive index of prism is sqrt2

A ray of light is incident at an angle of 60^@ on the face of a prism having refracting angle 30^@. The ray emerging out of the prism makes an angle 30^@ with the incident ray. Show that the emergent ray is perpendicular to the face through which it emerges and calculate the refractive index of the material of prism.
