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

3. A virtual image is fromed by plane mirror, convex mirror and concave lens..
