For a prism of refractive index, $1.732$ , the angle of minimum deviation is equal to the angle of prism. Then the angle of the prism is

Answer:

Solution:

We know $μ = \frac{sin (\frac{δ_{min} + A}{2})}{sin \frac{A}{2}}$
$A = δ_{\min}$

$∴$ $1 .732 = \frac{\sin A}{\sin \frac{A}{2}}$

$∴$ $A = 60 °$
