If the angle of prism is `60^@` and the angle of minimum deviation is also `60^@`, find the refractive index of the material of the prism.

Explanation

To find the refractive index of the material of the prism given that the angle of the prism \( A = 60^\circ \) and the angle of minimum deviation \( \delta_{min} = 60^\circ \), we can use the formula for the refractive index \( \mu \) of the prism:

\[ \mu = \frac{\sin\left(\frac{A + \delta_{min}}{2}\right)}{\sin\left(\frac{A}{2}\right)} \]
