NEET Physics (general) MCQ Question

Type: MCQ-conceptual-Hard-Class 12

Which of the following statements about the magnification in optical instruments is correct?

A

The total magnification is the product of the magnifications of the objective and eyepiece.

B

A larger focal length of the eyepiece increases the total magnification of the microscope.

C

The angular magnification is higher when the final image is formed at the near point compared to at infinity.

D

The magnification of a lens is always negative for real images.

Correct Answer

Option A

Detailed Explanation

The total magnification is indeed the product of the magnifications from the objective and the eyepiece, as stated in the equations provided. A larger focal length of the eyepiece would actually decrease the magnification, and the angular magnification at the near point is different compared to at infinity. While the magnification of a lens is negative for real images, it can be positive for erect images.
