Convex lens behaves like a simple microscope. The assertion is true.
View all questions of this test
The magnifying power of a convex lens is expressed as:
- For least distance of distinct vision,
- For relaxed eye, m = D/f
Since f is in the denominator, for larger magnifying power, focal length should be small. So, the reason is also correct and it is the assertion.

Directions : In the following questions, A statement of Assertion (A)...
Assertion (A): Convex lens behaves like a simple microscope.
Reason (R): For larger magnifying power, the focal length of convex lens should be small.
The correct answer is option A, i.e., Both A and R are true and R is the correct explanation of A.
Explanation:
A convex lens is a converging lens that is thicker at the center and thinner at the edges. It can be used as a simple microscope to magnify small objects. The convex lens forms a magnified virtual image of the object when it is placed closer to the eye than its focal length.
Reasoning:
The magnifying power of a simple microscope is given by the formula:
Magnifying Power (M) = 1 + (D/F)
Where D is the least distance of distinct vision and F is the focal length of the convex lens.
To increase the magnifying power of a simple microscope, the focal length of the convex lens should be small. This is because a smaller focal length allows for a larger angular magnification, which results in a higher magnifying power.
Conclusion:
The assertion and the reason both are true. The reason correctly explains why a convex lens behaves like a simple microscope. For larger magnifying power, a smaller focal length is required, and this can be achieved by using a convex lens with a smaller focal length.
Reason (R): For larger magnifying power, the focal length of convex lens should be small.
The correct answer is option A, i.e., Both A and R are true and R is the correct explanation of A.
