A compound micrscope consists of an objective lens of focal length 1.0 cm and an eyepiece lens of focal length 5.0 cm separated by 12.2 cm At what distance from the objective lens should an object be placed to focus it properly so that the final image is formed at the least distance of clear vision (25cm)? b. calculate the angular magnificationn in this case.

Explanation

To solve the problem step by step, we will follow the outlined approach:

### Step 1: Understand the Setup
We have a compound microscope consisting of an objective lens and an eyepiece lens. The focal lengths are given as:
- Focal length of the objective lens, \( f_o = 1.0 \, \text{cm} \)
- Focal length of the eyepiece lens, \( f_e = 5.0 \, \text{cm} \)
- Distance between the two lenses, \( d = 12.2 \, \text{cm} \)
