Real and Virtual Images:

Real and virtual images are two types of images that are formed when light rays pass through a convex lens. They are different in nature and have distinct characteristics.

Real Images:

Real images are formed when light rays converge at a point after passing through a convex lens. These images can be seen on a screen and are always inverted. Real images have the following characteristics:

- They can be projected on a screen.
- They are always inverted.
- They are formed when light rays converge.
- They are always on the opposite side of the lens from the object.

Examples of Real Images:

- A movie projector forms a real image on a screen.
- A camera forms a real image on the film.

Virtual Images:

Virtual images are formed when light rays appear to diverge from a point after passing through a convex lens. These images cannot be projected on a screen and are always upright. Virtual images have the following characteristics:

- They cannot be projected on a screen.
- They are always upright.
- They are formed when light rays appear to diverge.
- They are always on the same side of the lens as the object.

Examples of Virtual Images:

- A magnifying glass forms a virtual image.
- A plane mirror forms a virtual image.

Conclusion:

Real and virtual images are two types of images formed by a convex lens. Real images are formed when light rays converge while virtual images are formed when light rays appear to diverge. Real images can be projected on a screen while virtual images cannot. Real images are always inverted while virtual images are always upright.
