Questions
The displacement y of a particle in a medium can be expressed as where t is in second and x in metre. The speed of the wave is
detailed solution
Correct option is B
As given displacement equation of SHM, y=10-6sin100t+20x+π4 -------(1)Equation(1) comparing it with y=Asin(ωt+kx+φ) , we obtain ω=100rads-1,k=20Nm-1Speed of wave V=ωK=10020=5ms-1 .Talk to our academic expert!
