NEET Physics (general) MCQ Question
Which of the following statements about the magnification in optical instruments is correct?
The total magnification is the product of the magnifications of the objective and eyepiece.
A larger focal length of the eyepiece increases the total magnification of the microscope.
The angular magnification is higher when the final image is formed at the near point compared to at infinity.
The magnification of a lens is always negative for real images.
Correct Answer
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.
