Expert Answer:

The angle of deviation is the angle between the original incident ray and the emergent ray. Since the larger angle of deviation corresponds to a larger refractive index, violet light would emerge with the largest angle of deviation and red light would emerge with the smallest angle. Hence, the light emerging from the prism would disperse into a spectrum of rainbow colors wherein each color corresponds to a different angle of deviation.
