Question

Which part of the compound microscope helps in gathering and focusing light rays on the specimen to be viewed?

• A. Condenser lens
• B. Magnifying lens
• C. Objective lens
• D. Eyepiece lens

Hint:

The condenser lens is essential for controlling the light and contrast of the image in a compound microscope.

Answer 1

The Correct Option is A

The condenser lens in a compound microscope is responsible for gathering and focusing light rays from the light source onto the specimen. It helps in achieving optimal illumination of the specimen, which is critical for clear and sharp images.

(1) Condenser Lens:
- The condenser lens collects and concentrates light onto the specimen to ensure it is properly illuminated. It does not magnify the specimen directly but focuses light for the best image quality.

(2) Why Other Options Are Incorrect:
- Magnifying lens (Option 2) refers to the eyepiece or objective lenses, which magnify the image but are not responsible for focusing light on the specimen.
- Objective lens (Option 3) magnifies the specimen and helps in viewing the image, but it does not focus the light directly onto the specimen.
- Eyepiece lens (Option 4) is used for further magnification of the image formed by the objective lens and is not responsible for focusing light on the specimen.

Conclusion: The condenser lens is the part of the microscope that gathers and focuses light rays onto the specimen to provide proper illumination.
