The angle of minimum deviation for a glass prism with `mu=sqrt3` equals the refracting angle of the prism. What is the angle of the prism?

Explanation

Here, `mu = sqrt(3), delta_(m) = A`
From prism formula `mu = (sin (A + delta_(m))//2)/(sin A//2)`
`sqrt(3) = (sin A)/(sin A//2) = (2 sin A//2 cos A//2)/(sin A//2) = 2 cos A//2`
`cos A//2 = (sqrt(3))/(2) = cos 30^(@)`
`A//2 = 30^(@) or A = 60^(@)`
