Question

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

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

Answer 1

Answer: (A)

$6cm$

Since the object is placed at the centre all rays coming out will be $\perp$r to surface of sphere and hence no refraction takes place and the object appears as it in.
