The third harmonic frequency of a standing wave is 748 Hz on a string of length 99 cm that is bound at the two ends and is under tension. What is the speed of traveling waves on this string? A sinusoidal wave is given by: y= 10 sin {8x - 5t) cm determine the velocity of this wave in cm/s with two decimal places please. A transverse wave with a frequency of 859 Hz ,2 m wavelength, and 4 mm amplitude is propagating on a 3 m, taught wire. If the mass of the wire is 24 g, how much time in seconds does it take for a crest of this wave to travel the length of the wire? Please give your answer with two decimal places
