Find the angle of deviation suffered by the light ray shown in figure (18-E10). The refractive index μ = 1.5 for the prism material.


Refractive index of prism = μ = 1.5

Angle of prism =A =

We know that;


Angle of minimum deviation is given by =

(For small angles

So, the angle of deviation =.
