NEET Physics Optical Instruments MCQ Question
Which of the following statements regarding optical instruments is correct?
A simple microscope can achieve very high magnifications with a single lens.
The image formed by a concave mirror is always real and inverted.
Optical instruments operate based on the principles of reflection and refraction of light.
Total internal reflection occurs when light travels from a denser to a rarer medium at any angle.
Correct Answer
Detailed Explanation
Optical instruments utilize the principles of reflection and refraction of light to form images, as mentioned in the NCERT context. Option A is incorrect because a simple microscope has a limited maximum magnification. Option B is incorrect since the image by a concave mirror can also be virtual. Option D is incorrect as total internal reflection only occurs above a certain critical angle.
