The focal length of a simple convex lens used as a magnifier is 10 cm. For the image to be formed at a distance of distinct vision D = 25 cm, the object must be placed away from the lens nearly at a distance of

A convex lens of focal length 10 cm and imag formed by it, is at least distance of distinct vision then the magnifying power is

A convex lens of focal length 10 cm and imag formed by it, is at least distance of distinct vision then the magnifying power is

A converging lens of power 25 D is used as a simple microscoe.Calculae the magnifying power,if the distance of distinct vision is 25 cm.

The focal length of objective and eye lens of a microscope are 4 cm and 8 cm respectively. If the least distance of distinct vision is 24 cm and object distance is 4.5 cm from the objective lens, then the magnifying power of the microscope will be
