A diverging beam of light from a point source s having divergence angle ⍺, falls symmetrically on a glass slab as shown. the angles of incidence of the two extreme rays are equal. if the thickness of the glass slab is t and the refractive index n, then, find out the divergence angle of the emergent beam.
Since rays are just passing through the glass slab, they will suffer just in change in displacement. That would not... View Article
