NEET Physics Reflection MCQ Question
Which of the following statements about mirrors and lenses is correct?
The magnification of an image formed by a concave mirror is always positive.
A convex mirror always produces real images regardless of the object's position.
The image formed by a simple microscope at the near point is virtual and closer than infinity.
The focal length of a concave mirror is always positive according to the sign convention.
Correct Answer
Detailed Explanation
The image formed by a simple microscope at the near point is indeed virtual and closer than infinity, as stated in the context. Option A is incorrect because the magnification can be negative for real images. Option B is false as convex mirrors always produce virtual images. Option D is incorrect; the focal length of a concave mirror is considered negative in the sign convention.
