When the object is placed 4 cm from the ...

When the object is placed 4 cm from the objective of a microscope, the final image formed coincides with the object. The final image is at the least distance of distinct vision (24 cm). If the magnifying power of the microscope is 15, calculate the focal lengths of the objective and eye-piece.

Text Solution

Verified by Experts
