Consider the wave `y=(5mm)sin[(1cm^-1)x-(60s^-1)t]`. Find the amplitude, b. the wave number, c the wavelenth d. the frequencey e. the time period and f. the wave velocity.

Explanation

Comparing the given equation with equation (15.15, we find
a amplitude `A=5mm`
b. Wave number `k=1cm^-1`
c. wavelength `lamda=(2pi)/k=2picm`
`d =frequency v=omega/(2pi)60/(2pi)Hz`
`=30/piHz`
e. time period `T=1/v=pi/30s`
`f. wave velocity u=vlamda=60cms^-1`
