Real image
1. The image can be captured in a screen .
2.The image is always inverted.
3.Light rays actually meet to form a real image .
Virtual image
1.The image cannot be captured in a screen.
2.The image is always erect.
3.Light rays do not meet at a virtual point.

hi farman1. Nice to talk to you again.
Frnd,
There are two types of images which are formed by lenses which are as follows real image and virtual image.
★ REAL IMAGE-
Real image is formed by convex lens which is also known as converging lens. The convex lens converge the rays of light and a real image is formed. Convex lens has thick middle and thinner edges. And the point of formation of lens is called principal focus.
★ VIRTUAL IMAGE-
Virtual image is formed by concave lens which is called diverging lens. This image is formed when rays of light diverge from lens. Concave lens are thick at the edges and thinner at the middle.
What if we take,
REAL IMAGE Vs. VIRTUAL IMAGE
★ Formation:
Real images are formed by convex lens which converge the rays of light and image is formed.
Concave lens form Virtual Image and the rays do not intersect each other in contrary it is formed by diverging the rays of light.
★ Uses:
Real images are used in digital camera and projectors so it has vast use.
Virtual images are also formed in the mirror as the rays of light do not actually permit through the image.
★ Focal length-
Focal Length:
The focal length of real image is positive
The focal length of virtual image is negative
★ Formula:
The focal length can be calculated by using formula 1/f=1/d0+1/di. In case of converging lens the f will be greater than zero and di is for image formed at the right side and d0 is for object.
In case of virtual image the f will be less than zero and the di will be image formed at left side on the lens.
★ Reality:
Real image can be attained on monitor.
Virtual Image cannot be obtained on Screen.
★ Position of Image:
Real images are always overturned.
Virtual Image is always upright.
★ Examples:
Examples of Real image include images formed eye, digital camera and image formed by projector.
Image on mirror and on Television screen are some examples of virtual image
★ WHAT WE CONCLUDE:
We conclude that, both the real and inverted image are important in daily life as it is evident from the examples which are stated above it shows that the image which are viewed in normal life are of different types. They are formed by convex and concave lens respectively. Both these lens have many practical applications and are beneficial for human beings in many ways.
Hope it helped!
