NEET Physics Wave Motion MCQ Question
Which of the following statements about wave motion and characteristics is/are correct?
Mechanical waves require a medium for propagation and can be either transverse or longitudinal.
The amplitude of a wave is defined as the distance between two consecutive crests.
In a progressive wave, the particles of the medium oscillate in the same direction as wave propagation for transverse waves.
The phase of a wave determines the position of a point on the wave at a given time.
Correct Answer
Detailed Explanation
Statement A is correct as mechanical waves do require a medium and can be transverse or longitudinal. Statement B incorrectly defines amplitude; it refers to the maximum displacement, not the distance between crests. Statement C is incorrect for transverse waves, as they oscillate perpendicular to the direction of propagation. Statement D is correct, but it can be misleading without context about phase.
