Question

What are differences between real and virtual images formed by lenses?

Answer 1

Real images are formed in front of the mirror - however in lenses it is behind the lens.

Explanation:

In both cases, the image is formed by the convergence of actual light rays.

Virtual images are created behind a mirror or in front of a lens, both of which correspond to our brain constructing an imaginary image originating from the apparent source of the light ray (not the true source.)
