Answer:
The angle through which the emergent ray deviates from the direction of incident ray is called angle of deviation 'd'. As the angle of incidence is increased, angle of deviation 'd' decreases and reaches minimum value. If the angle of incidence is further increased, the angle of deviation is increased.
