Question

To see the image of an object formed by a lens, the object and the observer should be:

• A. on the same side of the lens
• B. on the different sides of the lens
• C. position of the observer does not matter
• D. can’t be said

Answer 1

The correct option is B

on the different sides of the lens

Lenses are made up of glass, which is a transparent material and hence light is able to pass through it. So the image can be seen only if the observer is on the other side of the lens with respect to the object.
