Detailed Solution

The angle of the prism is at 1 and the angle of deviation is at

9

.
The angle of a prism is defined as an angle formed due to two lateral faces of the prism. At the angle of the prism, the two lateral faces are from where the light enters the prism, and the light goes out after refraction. On the other hand, the angle of Deviation is defined as the angle between the incident and the emergent ray. At this angle, the light enters the first refracting surface of the prism; it gets refracted and is incident at the second refracting surface and emerges out at an angle of emergence from the prism. Now on the basis of the above definitions and facts, we can locate the angle of prism and angle of deviation.
