When a ray of light is refracted by a prism such that the angle of deviation is minimum then
Answer: A
At minimum deviation, the angle of emergence equals the angle of incidence.
The ray passes symmetrically through the prism, parallel to its base, so \(i = e\) and \(r_1 = r_2\). That symmetry gives the prism formula \[n = \frac{\sin\left(\frac{A+D_m}{2}\right)}{\sin\left(\frac{A}{2}\right)}\]
