A standing wave on a string of length L = 3 m fixed at both ends is described by: y(x;t) = 0.01sin(tx)cos(40t), where x and y are in meters and tis in seconds. The maximum transverse speed of an element on the string located at x = 1/6 m is: v_(y,max) = 0.2 m/s v_(y,max) = 0.6 m/s v_(y,max) = 0.3 m/s O v (y,max) = 0.4 m/s O v-(y,max) = 0.45 m/s

A standing wave has the following wave-function: y(x,t) = 0.2 sin(TIX) cos(12Ttt), where x and y are in meters, and t is in seconds. If the length of the string is L = 2 m and it is fixed at both ends, then the harmonic, n, in which the string is vibrating is: O n= 3 O n= 6 O n = 5 n = 2 n = 4 A standing wave with wavelength A = 1.2 m and frequency f = 50 Hz is generated on a stretched cord. For an element of the cord at x = 0.5 m, the maximum transverse velocity is v(y,max) = 2t m/s. The amplitude A of each of the individual waves producina the standing wave is:
