Answer:ray of monochromatic light is incident on one of the faces of an equilateral triangle prism of refracting angle A. Trace the path of ray passing through the prism. Hence derive an expression for the refractive index of material of the prism in terms of the angle of minimum deviation and its refracting. angle.
