What is the focal point of a lens?

Back

The focal point is the point where light rays converge or appear to diverge after passing through a lens.

What is the difference between real and virtual images?

Back

Real images can be projected on a screen and are formed by converging light rays, while virtual images cannot be projected and are formed by diverging light rays.
