The distance between the eyepiece and the objective lens in a certain compound microscope is 21.4 cm. The focal length of the objective is 0.480 cm, and that of the eyepiece is 1.50 cm. Find the overall magnification of the microscope. (The near point of the eye is 25 cm. Assume that the object is placed at the focal point of the objective lens, and one places the eyepiece at the near point of the eye.)

Expert Solution

The magnification of a compound microscope is given by:

where

L is the length of the microscope =21.4 cm

fo is the focal length of the objective =0.48 cm

d is the least distance od distant vision of human eye =25 cm

fe is the focal length of the eyepiece =1.5 cm

Using the formula we have

M=787.63

The proof has been given below

A certain microscope consists of an objective lens, (Lens 1), and a tube lens (Lens 2). The object is placed at the front focal plane of the objective lens and the image is at the back focal plane of the tube lens. The tube lens has a focal length of 200mm. The objective is labeled 20X, which means that the magnification will be 20 when used with this particular tube lens. The working distance (the distance from the object to...
