To find the angle of deviation for a light ray passing through a triangular prism, we first need to identify the given information and make a standard assumption about the prism.

To find the angle of deviation for a light ray passing through a triangular prism, we first need to identify the given information and make a standard assumption about the prism.

Given:
Refractive index of the material, $n = \frac{\sqrt{3}}{2}$.

Assumption:
A "triangular prism" usually refers to an equilateral prism unless specified otherwise. For an equilateral prism, the prism angle $A = 60^\circ$.

We need to find the angle of deviation, $\delta$. For minimum deviation, the formula relating the refractive index, prism angle, and minimum deviation angle is:
