A light is incident on face AB of an equilateral glass prism ABC. After refraction at AB, the ray is incident on face BC at the angle slightly greater than critical angle so that it gets reflected from face BC and finally emerges out from face AC. Net deviation angle of the ray is `112^(@)` anticlockwise. The angle of incidence 'i' has value:

If a ray of light is incident normally on any face of an equilateral glass prism, then the ray will be deviated through an angle

The face AC of a prism ABC of refracting angle 30^@ is silvered . A ray is incident on face AB at an angle of 45^@ as shown in figure . The refracted ray undergoes reflection at face AC and retraces its path . The refractive index of the prism is

A ray of light is incident making angle 36^@ with the face of an equilateral prism. If the ray suffers minimum deviation, the angle of deviation is :

A ray light is incident on a 60^@ prism at the minimum deviation position.The angle of refraction at the face (i.e.incident face)of the prism is:

(i) A ray of light incident on face AB of an equilateral glass prism, shows minimum deviation of 30^(@) . Calculate the speed of the light through the prism. (ii) Find the angle of incidence at face AB so that the emergent ray grazes along the face AC.

At what angle, a ray of light should be incident on the first face AB of a regular glass prism ABC so that the emergent ray grazes the adjacent face AC ?

(b) What is the angle of refraction from the first face of the prism ? (c) What will be the angle of incidence at the second face of the prism ?
