What is the lateral shift of a ray refracted through a parallel-sided glass slab of thickness ' $\displaystyle h$ ' in terms of the angle of incidence ' $\displaystyle i$ ' and angle of refraction ' $\displaystyle r$ ', if the glass slab is placed in air medium?
Official answer
From NTA’s final answer key for this paper.
(4)
$\displaystyle \frac{h \sin (i-r)}{\cos r}$
