Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Refraction at spherical surfaces occurs in two ways. The ray of light may travel from a rarer medium to a denser medium in which a ray of light bends towards the normal, or the ray of light may travel from a denser medium to a rarer medium in which the ray of light bends away from normal. Here, while considering the refraction at spherical surfaces, we assume: The object taken here is point sized, and is lying on the principal axis of the spherical refracting surface. The aperture of the spherical refracting surface is small. The incident and the refracted rays make small angles with the principal axis of the spherical surface so that sini≈i and sinr≈r.
