A sinusoidal wave on a string travelling in the +x direction at 8 m/s has a wavelength 2 m. (a) Find its wave number, frequency and angular frequency. (b) If the amplitude is 0.2 m, and the point x = 0 on the string is at its equi- librium position (y = 0) at time t = 0, find the equation for the wave.Solution: |
