NEET Physics Mirrors MCQ Question
Which of the following combinations about the properties of lenses and mirrors is correct?
A convex lens always produces a virtual image when the object is placed at its focal point.
The magnification produced by a concave mirror is positive for a real image and negative for a virtual image.
A lens with a shorter focal length provides greater magnifying power in a simple microscope.
The angle of incidence is always equal to the angle of refraction when light passes from a denser to a rarer medium.
Correct Answer
Detailed Explanation
A lens with a shorter focal length indeed provides greater magnifying power in a simple microscope, as stated in the NCERT context. While A and B contain inaccuracies regarding image types, D is incorrect because the angle of incidence equals the angle of refraction only under specific conditions.
