A convergent lens of power 16D is used as a simple microscope. The magnification produced by the lens, when the final image is formed at least distance of distinct vision is

A convex lens of focal length 5 cm is used as a simple microscope. What will be the magnifying power when the image is formed at the least distance of distinct vision ?

A convex lens of focal length 5cm is used as a simple microscope. What is the magnifying power, if final image is formed at the distance of distinct vision i.e. 25 cm ? If it is used as an eyepiece in a compound microscope with objective of magnifying power 40, what is the magnifying power of the compound microscope ?

Calculate the focal length of a lens used as simple microscope of magnifying power 20. Consider that the final image is formed at the least distance of distinct vision.
