NEET Physics Wave Motion MCQ Question

Type: MCQ-conceptual-Easy-Class 11

Which combination of statements about wave behavior and properties is correct?

A

The speed of sound in air is approximately 331.3 m/s at STP and is modified by the Laplace correction.

B

In the principle of superposition, waves can only cancel each other out, not add together.

C

The distance between two successive nodes in a stationary wave is λ, while the distance between antinodes is λ/2.

D

A traveling wave can be represented by the function y = f(x - vt) where v is the wave speed.

Correct Answer

Option A

Detailed Explanation

Statement A correctly describes the speed of sound in air and the Laplace correction as mentioned in the NCERT. Statement B is false because superposition allows for both addition and cancellation of waves. Statement C incorrectly states the distance between nodes and antinodes. Statement D is true, but does not provide an accurate representation of all wave functions.
