Question

A standing wave is formed on a string of a given tension, T, linear density, ?, and length, L. If the tension in the string is multiplied by two (T' = 2T) while maintaining the same frequency (f' = f) of the standing wave and the same linear density (?' = ?) and length of the string (L' = L), then the new number of loops, n', on this string is equal to the old number of loops, n, multiplied by a factor of: 1/4 2 ?2 1/?2 1/2 The wave functions for two waves traveling on a string are described by: y?(x,t) = A sin (?x - 40?t) and y?(x,t) = A sin (?x + 40?t) where, y and x are in meters, and t is in seconds. An element of the string oscillating vertically with amplitude A would be located at: x = (1/18) m x = (1/12) m x = (1/15) m x = (1/6) m
