A standing wave on a stretched string with a tension force F_T and of length L = 2 m has the following equation: y(x,t) = 0.1 sin(2Ttx) cos(100rt). How many loops %3D would appear on the string if the velocity is reduced by a factor of 3 while the frequency is held constant? 8 loops O 2 loops 6 loops O 12 loops O 4 loops

The wave function for a traveling wave on a taut string is (in SI units) TT y(x,t) = 0.340 sin | 14nt - 5TX + 4 (a) What are the speed and direction of travel of the wave?

Consider two tight strings, String A and String B. A wave travels on String A with a speed four times greater than the speed of a wave on String B. String A has twice the tension as String B. HA Which of the following is the ratio of densities of the strings: Ratio = HB 8 2 1 1/2 1/8

A standing wave pattern is created on a string with mass density p = 3 x 10-4  kg/m. A wave generator with frequency f = 62 Hz is attached to one end of the string and the other end goes over a pulley and is connected to a mass (ignore the weight of the string between the pulley and mass). The distance between the generator and pulley isL = 0.66 m. Initially the 2rd harmonic wave pattern is formed.   5)What is the wavelength of the wave?  6) What is the speed of the wave?  7) What is the tension in the string?  8) What is the mass hanging on the end of the string?  9) Keeping the frequency fixed at f = 62 Hz, what is the maximum mass that can be used to still create a coherent standing wave pattern?
