RE-NEET 2024 Physics Wave Equation MCQ Question

Type: MCQ-conceptual-Medium-Class 11

The displacement of a travelling wave y = C sin(2π/λ (at − x)) where t is time, x is distance and λ is the wavelength, all in S.I. units. Then the frequency of the wave is:

A

2πv/a

B

2πa/λ

C

λ/a

D

a/λ

Correct Answer

Option D

Detailed Explanation

The wave equation y = C sin(2π/λ (at − x)) implies that the angular frequency ω = 2πa/λ, so the frequency f = a/λ.
