Question

concave mirror has real focus whereas convex mirror has virtual focus . draw ray diagrams to support your answer

Answer 1

The focus, or rather the Principle Focus is the point in which parallel beam of light, after reflection, converges or appears to diverge from.

The Principle Focus of a concave mirror is in front of the mirror whereas the Principle Focus of a convex mirror is behind the reflecting surface.

Principle Focus is denoted as 'F' in ray diagrams:
