A flint glass pri

Given that,

Refracting angle of flint prism= A_f = 6.0°

Refractive index of flint glass =μ_f = 1.620

Refractive index of crown glass =μ_c =1.518

Now,

Let the refractive angle of the crown prism be A_c.
For the net deviation of the mean ray to be zero,
Deviation by the flint prism = Deviation by the crown prism
