Question

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

• A. $6cm$
• B. $4cm$
• C. $12cm$
• D. $9cm$

Answer 1

The correct option is A $6cm$

Since, the object is kept at the centre from the sphere all the rays coming from it are normal to the surface of the sphere.

Therefore they will emerge out undecided.

The image will appear at the same place i.e, 6 cm from the surface.
