Question

What is differnce between real image and virtual image ? Give one example of each type of Image .

Answer 1

The following are the differences between a real image and virtual image:

A real image can be caught on a screen whereas a virtual image cannot be caught on a screen.A real image is always inverted whereas a virtual image is always erect.A real image is formed when the rays of light after reflection or refraction actually meet at some point whereas a virtual image is formed when the rays of light after reflection or refraction appear to meet at a point.A real image is formed by the actual intersection of light rays whereas a virtual image is formed by the imaginary intersection of light rays.A real image can be formed in in a intersection of light rays whereas a virtual image is formed by the imaginary intersection of light rays.A real image can be formed in in a screen but a virtual image can be only seen in the mirror.A real image is formed by only concave mirror however a virtual image can be formed by concave, convex and plane mirror also.

Answer 2

Real image will form when two light rays intersect to form a image. for example image formed by convex lens.
Virtual image will form when the light rays don't intersect each other and image will be the same size as object size. for example image formed by plane mirror
