A tuning fork is in resonance with a vibrating string under tension. When the tuning fork is moved with a certain velocity, 2 beats per second are heard. If the tension is increased, the beats disappear again. The direction of motion of the tuning fork is

Two tuning forks when sounded together produce 3 beats per second. On loading one of them with a little wax, 20 beats are heard in 4 seconds. Find its frequency if that of other is 386.

A vibrating string of certain length l under a tension T resonates with a maode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also gereates 4 beats per second when excited along with a tuning fork of frequency n . now when the tension of the string is slightly increased the number of beats reduces 2 per second. assuming the velocity of sound in air ti be 340 m//s , the frequency n of the tuning fork in Hz is

A string 25cm long and having a mass of 2.5 gm is under tension. A pipe closed at one end is 40cm long. When the string is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. It is observed that decreasing the tension in the string decreases beat frequency. if the speed of sound in air is 320m//s , find the tension in the string.

A string 25 cm long fixed at both endds and having a mass of 2.5 g is under tension. A pipe closed from one end is 40 cm long. When the strin is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. If is observed that decreasing the tension in the string decreases the beat frequency. If the speed of sound in air is 320 m//s . Find tension in the string.

A tuning fork of unknown frequency vibrates in unison with a wire of certain stretched under a tension of 5 kg f. It produces 6 beats per second with the same wire, when tension is changed to 4.5 kg f. Find the frequency of tuning fork.

(i) A wire is stretched between two rigid supports. It is observed that the wire resonates at a frequency of 420 Hz. If a wooden bridge is placed at the midpoint of the wire (so that the midpoint becomes a node), it was observed that the smallest frequency at which the wire resonates is 420 Hz. Find the smallest frequency at which the wire will resonate when there is no wooden bridge. (ii) A string of length L is fixed at one end and is under tension due to a weight hanging from the other end, as shown in the figure. The point of the string on the pulley behaves as a fixed point. Coordinate axes are chosen so that the horizontal segment of the string runs from x = – L // 2 to x = L // 2 . The string is vibrating at one of its resonant frequencies with transverse displacement (y) given by y(x,t) = 0.05 cos(12.0x) sin(360t) with x, y in meter and t in second. Write two smallest possible values of L consistent with the given equation?

A vibrating string produces 2 beats per secod when sounded with a turning fork of frequency 256Hz . Slightly increasing the tension in the string produces 3 beats per second. The initial frequency of the string may have been

Two tuning forks A and B produce 8 beats per second when sounded together ,When B is slightly loaded with wax the beats are reduced to 4 per second .If the frequency of A is 512 Hz,the frequency of B is

(a) A tuning fork produces 4 beats per second with another tuning fork of frequency 256 Hz . The first one is now loaded with a little wax and the beat frequency is found to increase to 6 per second. What was the original frequency of the tuning fork ? (b) A plano wire A vibrates at a fundamental frequncy of 600 Hz . A second identical wire B produces 6 betas per second with it, when of the tension in A is slightly increased. Find the ratio of the tension in A to the tension to B . ( c) A tunnig fork if frequency 256 Hz produces 4 beats per second with a wire of length 25 cm vibrating in its fundamental mode. The beat frequency decreases when the length is slightly shortened. What could be the minimum length by whech the wire be shortened so that it produces no beats with the tuning fork?
