Wave of frequency 200hz is produced in a string .qHere amplitude is 5

1.	Wave of frequency 200hz is produced in a string .qHere amplitude is 5 cmWavelength is 10cm Find velocity
Answer» $\underline{\underline{\Large{\bf Given:-}}}$ $\bull\sf Frequency=f=200Hz$ $\bull\sf Amplitude=A=5cm$ $\bull\sf Wavelength=\lambda=10cm=10^{-1}m$ $\underline{\underline{\Large{\bf To\:Find:-}}}$ $\bull\sf Velocity=\nu$ $\underline{\underline{\Large{\bf Solution:-}}}$ We KNOW $\boxed{\sf v=f\lambda}$ $\\ \sf\longmapsto \nu=200\times 10^{-1}$ $\\ \sf\longmapsto \nu=20m/s$ $\underline{\underline{\therefore{\sf Velocity\:of\:wave\:is\:20m/s.}}}$
