A particle on a stretched string support...

A particle on a stretched string supporting a travelling wave, takess `5.0 ms` to move from its mean position to the extreme position. The distance between two consecutive particle, which are at their mean position, is `3.0 cm`. Find the wave speed `(in m//s)`.

Text Solution

Verified by Experts

Time period
`T=4xx5 ms=20xx10^(-3)=2xx10^(-2)s`
Frequency, `f=(1)/(T)=(1)/((2xx10^(--2)))=50 Hz`
`lambda=2xx3 cm=6 cm`
wave speed: `v=lambdaf=0.06xx50=3 m//s`
