Document Summary
Section a each question is worth 1 mark. A string under tension carries transverse waves traveling at speed v. if the same string is under four times the tension, what is the wave speed: v b) 2v c) v/2 d) 4v e) v/4. A wave is traveling with a speed v along the x axis in the positive direction. The upper graph shows the displacement y versus the distance x for a given instant of time. The lower graph shows the displacement y versus the time t for any given point x. From the information in the graphs, what is the wave speed v: 8. 0 m/s, 4. 0 m/s, 6. 0 m/s, there is not enough information to solve the problem, none of these is correct. A sound source of frequency f moves with constant velocity (less than the speed of sound) through a medium that is at rest. A string fixed at both ends is vibrating in a standing wave.
