Question

Note: can’t use the magnification of a microscope formula 2. The distance between the eyepiece and the objective lens in a certain compound microscope is 20.0 cm. The focal length of the objective is 0.500 cm, and that of the eyepiece is 1.70 cm. Calculate the overall magnification of the microscope, assuming that the cyepiece of the microscope has be en r maximum magnification. Note: This problem is to be solved using first principles (the lens equation). You may ignore the distance between the eye and the eyepiece lens. You may not use equation 25.7 to solve this problem.

Explanation / Answer

overall magnification of microscope is

M = -LS/fofe

M = - 20cm *25 cm/(0.5cm*1.7cm)

M = -588.235

-ve means final image is real and inverted
