If the image formed by a thin convex lens of power P has agnification m then image distance v is

If the image formed by a thin convex lens of power P has magnification m then image distance v is

The image formed by a convex lens

A real image formed by a convex lens is always-

In which case the image formed by a convex lens is virtual ?

The image formed by a convex lens is always real. Is it true?

The image formed by convex lens in a simple microscope is

The distance between the object and the real image formed by a convex lens is d. If the linear magnification is m, find the focal length of the lens in terms of d and m.

Write two characteristics of image formed when an object is placed between the optical centre and focus of a thin convex lens. Draw the graph showing variation of image distance v with object distance u in this case.
