The focal length of the eye-piece of compound microscope is

If f_0 and f_e , are respective focal lengths of objective and eye-piece of compound microscope, then ......

The focal length of the objective and of the eye- piece of compound microscope are f_(0) and f_(e) respectively. If L is the tube length and d, the least distance of distinct vision, then its angular magnification, when the image is formed at infinity, is

The focal length of the objective lens of a compound microscope is

The focal length of the objective lens of a compound microscope is

The focal length of objective and eye-piece of a compound microscope are 1 cm and 5 cm respectively. The microscope magnification is equal to 50. If the distance between two lenses is increased by 2 cm then the magnification is

The focal length of th eye-piece and ojective a compound microscope are 5 cm and 1 cm respectively and the length of the tube is 20 cm.Calculate he magnifying power of the microscope,when the final image is formed at infinity .The value of least distance of ditinct vision is 25cm.

A : The objective and the eye-piece of a compound microscope should have short focal lengths. R : Magnifying power of a compound microscope is inversely proportional to the focal lengths of both the lenses.
