NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about wave optics is correct?
A
A plane polarised wave has its displacement at right angles to the direction of propagation.
B
An unpolarised wave has a fixed plane of vibration.
C
Transverse waves cannot be described by sinusoidal equations.
D
The principle of conservation of energy does not apply to wave interference.
Correct Answer
Option A
Detailed Explanation
A plane polarised wave is indeed characterized by the displacement being at right angles to the direction of propagation, consistent with the description in the NCERT context. The other statements reflect common misconceptions about wave properties.
