Detailed Solution

Concept- By maintaining the point object at a specific distance from the sphere's first surface in order to acquire its image at infinity (since the image is real) from the second surface, we may make a ray diagram.Given: A transparent sphere of radius

R

and refractive index

μ

is kept in the air.
To find the distance from the surface of the sphere where a point should be placed so as to form a real image at the same distance from the other side of the sphere
Using the equation,
