Question

Refraction at Concave Spherical Surface
when Object lies in Rarer Medium​

Answer 1

Answer:

We consider refraction from rarer to denser medium at a concave spherical refracting surface. In this case, suppose an object O is lying on the principal axis of a spherical refracting surface KL, which is concave towards the rarer medium and forms virtual image.

Answer 2

Answer:

Refraction at a concave spherical refracting surface

We consider refraction from rarer to denser medium at a concave spherical refracting surface. In this case, suppose an object O is lying on the principal axis of a spherical refracting surface KL, which is concave towards the rarer medium and forms virtual image.
