Question
A progressive wave having amplitude 5 m and wavelength 3 m. If the maximum average velocity of particle in half time period is 5 m/s and wave is moving in the positive x-direction then find which may be the correct equation(s) of the wave? [where x in meter]
Options
A.5 sin 
B.4 sin 
+ 3 cos 
+ 3 cos C.5 sin
D.3 cos 
- 4 sin
- 4 sin Solution
∵ λ = 3m ∴ k = 
Maximum displacement in half time period = 2a = 10 m
So maximum average velocity =
⇒ T = 4s ⇒ 
Maximum displacement in half time period = 2a = 10 m
So maximum average velocity =
⇒ T = 4s ⇒ Create a free account to view solution
