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.
