A continuous succession of sinusoidal wave pulses are generated at one end of a very long string and travel all along the length of the string. The wave consists of frequency 38.0 Hz, amplitude 4.55 mm, and wavelength of 0.650 m.
(i) Determine how long does it take the wave to travel a distance of 8.10 m all along the length of the string?
(ii) Determine how long does it take a point on the string to travel a distance of around 8.10 m, once the wave train has reached the point and set it to the motion?
