what is the difference between image and shadow??????????

Hi Priti ,

Shadow is formed by obstruction of light by an opaque object. One cannot readily identify something by its shadow. For example, some people can make different structures look -alike of animals etc. only by their hands.

Image,on other hand, is a true reflection of body. It is formed by reflection of light rays by an object. You are able to see something only when reflected rays from a body make an image in your eyes.

Hope it is clear!
Cheers!!

A shadow is formed in a region where there is no light shining on it. It is distinctive to the human eye because the area surrounding the shadow has light and there will thus be a contrast. A shadow is not a tangible thing, neither is it an illusion, because it is not formed by light rays but rather, the absence of it. 
 
On the other hand, an image, say one that is formed when you look into a mirror, or when light passes through some lens, is caused by light rays. An image can be real or virtual. Real images can be captured on a screen, while virtual images cannot be caught on a screen.
