For a glass prism ( $μ = 2$ ) the angle of minimum deviation is equal to the angle of the (refracting) prism. The angle of the prism is:

Answer:

Solution:

$δ_{m} = A$ , so $μ = \frac{sin A}{sin ( A /2 )} = 2 cos \frac{A}{2}$

$cos \frac{A}{2} = \frac{2}{2}$

$\frac{A}{2} = 4 5^{\circ}$

$A = 9 0^{\circ}$
