Why should the objective of a microscope be of small aperture ?
Text Solution

### Step-by-Step Solution:
1. **Understanding the Microscope Objective**: The objective lens of a microscope is responsible for gathering light from the specimen and forming a magnified image.
2. **Concept of Aperture**: The aperture of a lens refers to the opening through which light enters. A small aperture means that the lens can only gather a limited amount of light.
3. **Light Gathering and Brightness**: When the objective has a small aperture, it allows for better control over the light rays coming from the specimen. This results in a focused and bright image because the light rays converge more effectively.
