A sinusoidal wave travelling in the positive x direction has an amplitude of 15 cm, wavelength 40 cm and frequency 8 Hz. The vertical displacement of the medium at t =0 and x = 0 is also 15 cm, as shown

(a) Find the angular wave number, period angular frquency and speed of the wave.

Text Solution

Verified by Experts

`k=(2pi)/(lambda)=(2pirad)/(40cm)=(pi)/(20)rad//cm`
`T=1/f=1/8s omega =2pif=16s^(-1)`
`v=flambda=320cm//s`
