Question

A point object is placed at the centre of a glass sphere of radius $6\text{cm}$ and refractive index $1.5$. The distance of the virtual image from the surface of the sphere is

• A. $2\text{cm}$
• B. $4\text{cm}$
• C. $6\text{cm}$
• D. $12\text{cm}$

Answer 1

The correct option is C $6\text{cm}$

All rays coming from the object at the centre of the sphere are normal. So, no bending will take place.
