Question

Distinguish between a real and a virtual image.

Answer 1

	Real image	Virtual image
1.	When the rays of light diverging from a point after reflection or refraction actually converge at some point, then that point is the real image of the object.	When the rays of light diverging from a point after reflection or refraction appear to diverge from some other point.
2.	A real image is always inverted and can be taken on the screen.	A virtual image is always erect and cannot be taken on the screen.
3.	A real image is formed by eye, photographic camera, convex lens except when the object is very close to a concave mirror.	A virtual image is formed by a plane mirror, a convex mirror and a concave lens.
