REFRACTION THROUGH A COMPOUND SLAB

Consider two parallel slabs having refractive index andare kept one above the other. The medium above and below the compound slab is the same. If we consider refraction of light at the interface of ‘a’ and ‘b’, then Now consider refraction of light at the interface of ‘b’ and ‘c’, then Considering refraction of light […]

REFRACTION AT A SPHERICAL SURFACE

  Let us consider, LMN represents a ‘convex’ spherical surface of radius of curvature ‘R’ of refractive index ‘’. Consider a point object ‘O’ on the principal axis situated in an optically rarer medium of . . A ray ‘OA’ incident at an angle ‘i’ is refracted along ‘AI’. Another ray ‘OM’ incident normally on […]
