A string under a tension of 100 N , emitting its fundamental mode , gives 5 beats//s with a tuning fork. When the tension is increased to 121 N , again 5 beats//s are heard. The frequency of the fork is

A piano note is compared to a tuning fork vibrating at 440 Hz. Three beats per second are listened by the piano tuner. When the tension in the string is increased slightly, the beat frequency increases. What was the initial frequency of the piano wire ?

A sonometer wire vibrating in first overtone has length of 31.25cm . Tensio in the wire is 256N and mass per unit length is 10gm//m . When it is sounded together with a tuning fork 10 beats are heard. If tension in the wire is slightly increased no beats are heard. What is the possible frequency of the tuning fork ?

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 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 to be 340 m//s , the frequency n of the tuning fork in Hz is

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 ?
