A student tunes his guitar by striking a 120 Hertz with a tuning fork, and simultaneously plays the 4th string on his guitar. By keen observation, he hears the amplitude of the combined sound oscillating thrice per second. Which of the following frequencies is the most likely the frequency of the 4th string on his guitar?
Compare the velocities of the wave forms given below, and choose the correct option.
where, vA, vB, vC and vD are velocities given in (a), (b), (c) and (d), respectively.
The displacement y of a wave travelling in the x direction is given by y = (2 x 10-3) sin `(300 "t" - 2x + pi/4)`, where x and y are measured in metres and t in second. The speed of the wave is:
A uniform rope having mass m hangs vertically from a rigid support. A transverse wave pulse is produced at the lower end. Which of the following plots shows the correct variation of speed v with height h from the lower end?
