At \(t = 0\), a transverse wave pulse travelling in the positive \(x\) direction with a speed of \(2\;m/s\) in a wire is described by the function \(y=\dfrac{6}{x^{2}}\), given that \(x \neq 0\). Transverse velocity of a particle at \(x=2 m\) and \(t=2\) seconds is

The equation of a wave is given by: \(y=10 \sin \left(\dfrac{2 \pi t}{30}+\alpha\right)\)If the displacement is \(5\,cm\) at \({t=0}\), then the total phase at \({t=7.5 {~s}}\) will be

A wave is expressed by the equation \({y=0.5 \sin \pi(0.01 x-3 t)}\), where \({v}\) and \({x}\) are in metre and \({t}\) in second. The speed of propagation is
1 \(100\,m/s\)
2 \(300\,m/s\)
3 \(210\,m/s\)
4 \(500\,m/s\)
Explanation:
Wave equation is \({v=0.5 \sin \pi(0.01 x-3 t)}\) Comparing with standard wave equation \({y=A \sin (\omega t-k x)}\) we get \({A=0.5 {~m}}\) \({\omega=3 \pi {rad} / {s}}\) \({k=0.01 \pi {m}^{-1}}\) Wave speed is given as \({v=\dfrac{\omega}{k}=\dfrac{3 \pi}{0.01 \pi}=300 {~m} / {s}}\)
