Atransverse wave with a frequency of 787 Hz ,6 in wavelength, and 2 mm amplitude is propagating on a 2 m, taught wire. If the mass of the wire is 54 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. The third harmonic frequency of a standing wave is 626 Hz on a string of length 65 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= 1 sin (6x - 8t) cm determine the velocity of this wave in cm/s with two decimal places please.A sinusoidal wave is given by: v= 5 sin (3x - 4t) {:m determine the transverse velocity W of a point on this wave in cmfs at point x =8 cm for t=3 s
