NEET Physics Mirrors MCQ Question
Which of the following combinations correctly describe the relationship between focal length, magnification, and lens type in optical instruments?
A shorter focal length in a convex lens increases magnifying power.
The magnifying power of a simple microscope is directly proportional to the focal length of the lens.
Both objective and eyepiece of a compound microscope should have long focal lengths.
A convex lens with a very small focal length can achieve high magnifying power.
Correct Answer
Detailed Explanation
A shorter focal length indeed increases the magnifying power of a convex lens, as stated in the NCERT context. Options B and C are incorrect as they misinterpret the relationships outlined in the text.
