NEET Physics Wave Motion Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): The wavelength of a wave is the distance between two consecutive points having the same phase.

Reason (R): In a sinusoidal wave, the wavelength is given by the formula λ=2πk\lambda = \frac{2\pi}{k}.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

According to Chunk 3, wavelength is the minimum distance between two points having the same phase, and is given by λ=2πk\lambda = \frac{2\pi}{k}, thus R explains A.
