If we need a magnification of `375` from a microscope of tube length `15 cm` and an objective of focal length `0.5 cm`, what focal length eye lens should be used ?

Text Solution

AI Generated Solution

To solve the problem step by step, we will use the formula for magnification in a compound microscope and the given values. ### Step 1: Understand the given data - Magnification (M) = 375 - Tube length (L) = 15 cm - Focal length of the objective lens (F₀) = 0.5 cm - Distance of distinct vision (D) = 25 cm ...
