Physics-Wave Motion

NEET Physics Wave Motion MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which of the following statements about wave motion is correct?

A

A wave propagates energy through a medium without the permanent displacement of the medium itself.

B

The wavelength of a wave is always equal to its amplitude.

C

In wave motion, the speed of the wave depends solely on the frequency of the wave.

D

All waves require a medium to propagate, including electromagnetic waves.

Correct Answer

Option A

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.
