A convex lens is thick in the middle and it tapers at the ends. Parallel rays converge to a point when they pass through a convex lens. Concave lens is thin at the middle and thick at the edges. Rays of light appear to diverge from a point on the concave lens.

A real image is obtained through the actual intersection of rays of light, whereas, if the rays do not actually meet, but appear to meet when produced backwards, the image is virtual.

What is the difference between a converging lens (convex) and a diverging lens (concave)?
A convex lens is thick in the middle and it tapers at the ends. Parallel rays converge to a point when they pass through a convex lens. Concave lens is thin at the middle and thick at the edges. Rays of light appear to diverge from a point on the concave lens.

See lessWhat do you mean by an object at infinity?
When an object is at a large distance from the lens as compared to the focal length of the lens, the object is said to be at infinity.

See lessHow is an image formed in a lens?
The image is formed as a result of refraction of light rays that fall on the lens material.
