The displacement of the particle at x = ...

The displacement of the particle at x = 0 of a stretched string carrying a wave in the positive x-direction is given by `f(t)=Asin(t/T)`. The wave speed is v. Write the wave equation.

Text Solution

Verified by Experts

The correct Answer is:
A
At `x=0, f(t)=a sin (t/T)`
wave speed =v
`rarr lamda=wavelength
`=vT(T=` Time period)`
So, general of equation of wave
`y=Asin[(t/T)-(x/(vT))]
