Please tell me the difference between concave lens and convex lens

Explanation:

A concave mirror can form a real and inverted image. When the object is

placed very close to the mirror, the image formed is virtual, erect and

magnified.

Image formed by a convex mirror is erect, virtual and smaller in size

than the object.

A convex lens can forms real and inverted image. When the object is

placed very close to the lens, the image formed is virtual, erect and

magnified. When used to see objects magnified, the convex lens is called

a magnifying glass.

A concave lens always forms erect, virtual and smaller image than the

object.
