For the angle of minimum deviation of a prism to be equal to its refracting angle, the prism must be made of a material whose refractive index

Answer:

Solution:

$μ = \frac{sin ( \frac{A + δ m}{2} )}{sin A /2} = \frac{sin ( \frac{A + A}{2} )}{sin A /2}$
In given situation value of $A$ varies from 0 to $9 0^{\circ}$ . So, $μ_{m i n} = 2 cos \frac{9 0 ^{\circ}}{2} = 2$ and $μ_{m a x} = 2 cos 0^{\circ} = 2$
