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...
