An angular magnification (magnifying power) of `30 X` is desired using an objective of focal length `1.25 cm` and an eye piece of focal length `5 cm`. How will you set up the compound microscope ?

Explanation

To set up a compound microscope with an angular magnification of 30X using an objective lens with a focal length of 1.25 cm and an eyepiece with a focal length of 5 cm, follow these steps:

### Step 1: Understand the relationship between total magnification and individual magnifications
The total angular magnification (M) of a compound microscope is given by the product of the magnification of the objective lens (M₀) and the magnification of the eyepiece (Mₑ):
\[ M = M₀ \times Mₑ \]
Given that \( M = 30 \), we need to find \( M₀ \) and \( Mₑ \).

### Step 2: Calculate the magnification of the eyepiece
