A glass slab ABCD is made of two different grades of glass of refractive indices `3/2 and 4/3` of equal thickness, and a ray PQ is incident on the face AB. Trace the ray as it passes through the slab and find the angle of emergence and the angle of deviation, Find the effective refractive index of the slab.

(i) Apparent shift ` = t(1-1/mu)`
Find the apparent shift in each glass slab `S_(1) and S_(2)` and the total shift (S) = `S_(1) + S_(2)`
But `S = t(1-1/mu_(e))` when `mu_(e)` is the effective refractive index
(ii) `mu = 24/17`
