A. 30.0°
B. 37.2°
C. 42.0°
D. 48.6°
Correct Answer:
Option B – 37.2°
A ray of light is incident on an equilateral triangular glass prism of refractive index 3/2. Calculate the angle through which the ray is minimally deviated in the prism?
![A ray of light incident at an angle θ in a rectangular prism grazes the surface of the prism on emerging from the prism. Determine the value of the angle. [Absolute refractive index of the material of the prism is 1.5]](https://erudites.ng/wp-content/plugins/contextual-related-posts/default.png "A ray of light incident at an angle θ in a rectangular prism grazes the surface of the prism on emerging from the prism.
