Question

a small angle of prism 1.7 refractive index to have 4.9° deviation than prism angle is what..?​

Answer 1

Answer:

The smallest angle through which light is bent by an optical element or system. In a prism, the angle of deviation is a minimum if the incident and exiting rays form equal angles with the prism faces. The angle is important relative to prism spectroscopes because it can be easily determined.
