NTA Abhyas JEE Main2020PhysicsWaves and SoundPractice
The equation of a simple harmonic progressive wave is given by y = A sin 100 π t - 3 x . Find the distance between 2 particles having a phase difference of π 3 .
Options
- Aπ 9 m
- Bπ 18 m
- Cπ 6 m
- Dπ 3 m
Correct answer
A. π 9 m
Step-by-step solution
Given, y = A sin 100 π t - 3 x The general equation, y = A sin ω t - k x ∴ k = 3 Phase difference, ϕ = π 3 K x = π 3 x = π 3 k x = π 9 Distance, x = π 9 m
