Answer:

A convenient way to measure the refractive index of a prism is to direct a light ray through the prism such that it produces the minimum deviation angle. ... The angle of minimum deviation is attained when the angle of incidence and angle of emergence for a ray of light being refracted through a prism, are equal.
