Question

Which of the following lens are used in the microscope?

• A. Convex lens
• B. Concave lens
• C. Curved lens
• D. Cataract lens

Hint:

Remember that convex lenses are used in optical instruments like microscopes because they help focus light to create magnified images.

Answer 1

The Correct Option is A

In microscopes, convex lenses are used because they converge light to form a clear image of small objects.
Concave lenses, curved lenses, and cataract lenses are not typically used in microscopes.
Thus, the correct answer is option (1).

Answer 2

Microscopes primarily use convex lenses to magnify small objects for detailed observation.

Role of Convex Lenses in Microscope:
Convex lenses are converging lenses that bend light rays inward to focus them and create a magnified image.
In a compound microscope, there are usually two convex lenses: the objective lens and the eyepiece lens.

How It Works:
- The objective lens, placed close to the specimen, produces a real, inverted, and magnified image.
- This image is then further magnified by the eyepiece lens, which acts like a magnifying glass.

Importance of Convex Lenses:
Convex lenses are essential because they allow microscopes to achieve high levels of magnification and resolution.
They help in observing tiny details that are invisible to the naked eye.

Summary:
- Microscopes use convex lenses.
- Both objective and eyepiece lenses are convex.
- They work together to magnify small objects.

Convex lenses are fundamental components enabling microscopes to reveal microscopic structures.
