NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about wave optics and polarization is correct?
A
Linearly polarized waves always propagate in the direction of displacement.
B
Unpolarized waves have a fixed plane of vibration that does not change.
C
Transverse waves have displacements that are perpendicular to the direction of wave propagation.
D
Polarized waves can randomly change their displacement direction over time.
Correct Answer
Option C
Detailed Explanation
Transverse waves, such as linearly polarized waves described in the context, have displacements at right angles to the direction of propagation, as stated in the NCERT context. In contrast, unpolarized waves do not have a fixed plane of vibration and can change randomly.
