You generate a standing wave on a 1-m long string, fixed on both ends, by forcing it to vibrate at 100 Hz. When doing so, the standing wave has a wavelength of 1 m. According to the wave equation, v=Af, the speed of the wave along the string is 100 m/s. Suppose the forcing frequency is doubled to 200 Hz, without changing the length, tension or ends of the string. What is the new wavelength and wave speed? A. The...

A standing wave pattern is created on a string with mass density u- 3x 10 kg/m. A wave generator with frequency f- 65 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 is L- 0.74 m. Initially the 3rd harmonic wave pattern is formed. What is the wavelength...
