The displacement of a particle in a medi...

The displacement of a particle in a medium can be expressed as
`y=10^(-6)sin(100t+20x+pi//4),`
where x is in metre and t is in second. What is the speed of the wave?

Text Solution

Verified by Experts

Compare the given equation with the standard from `y=rsin(omegat+kx=phi_(0))`
`omega=100rad//s,k=20m^(-1)`
Speed of wave , `v=(omega)/(k)=(100)/(20)=5m//s`
