NEET Physics Wave Motion MCQ Question
Which of the following statements about wave motion is correct?
A wave propagates energy through a medium without the permanent displacement of the medium itself.
The wavelength of a wave is always equal to its amplitude.
In wave motion, the speed of the wave depends solely on the frequency of the wave.
All waves require a medium to propagate, including electromagnetic waves.
Correct Answer
Detailed Explanation
Statement A is correct as it describes how waves transfer energy through a medium while the medium itself experiences only temporary disturbances. Statement B is incorrect because wavelength and amplitude are distinct properties. Statement C is misleading as wave speed is determined by the medium's properties and both frequency and wavelength. Statement D is wrong because electromagnetic waves can propagate in a vacuum.
