Question

Draw a ray diagram showing refraction of light passing through an equilateral prism under minimum deviation condition. A ray of light incident on the refracting face of an equilateral prism in such a way that the angle of incidence is equal to the angle of emergence and each of these angle is ¾ times the angle of prism (A). Determine the (i) the angle of deviation and (ii) speed of light inside the prism material???
