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.

A simple microscope has a magnifying power of 4.125, when the image is formed at the distance of distinct vision. What is the focal power of the lens ?

When the magnification of converging lens is +1, then the image formed is:

In compound microscope the magnification is 95, and the distance of object from objective lens 1/3.8 cm and focal length of objective is ¼ cm. What is the magnification of eye pieces when final image is formed at least distance of distinct vision :

A lens of power 16D is used as a simple microscope. In order to obtain maximum magnification, at what distance from the lens

The magnifying power of a simple microscope is 6. The focal length of its lens in metres will be, if least distance of distinct vision is 25cm

What is the magnifying power of a simple microscope of focal length 5 cm, if the image is formed at the distance of distinct vision ?
