When a vibration tuning fork is placed on a sound box of a sonometer, 8 beats per second are heard when the length of the sonometer wire is kept at 101cm or 100cm. Then the frequency of the tuning fork is (consider that the tension in the wire is kept constant)

A sonometer wire under tension of 63 N vibrating in its fundamental mode is in resonance with a vibrating tuning fork. The vibrating portion of that sonometer wire has a length of 10 cm and a mass of 1 g. The vibrating tuning fork isnow moved away from the vibrating wire with a constant speed and an observer standing near the sonometer hears one beat per second. Calculate the speed with which the tuning fork is moved if the pseed of sound in air is 300 m/s.

    A strctcjed sonometer wire is in unison with a tuning fork of frequency 440 Hz. What will be the frequency of the wire if. Keeping the tension constant, the vibrating length of the wire is increased by 10 \%?

    A sonometer wire under tension of 64 N vibrating in its fundamental mode is in resonance with a vibrating tuning fork. The vibrating portion of the sonometer wire has a length of 10 cm and mass of 1 kg. The vibrating tuning fork is now moved away from the vibrating wire with a constant speed and an observer standing near the sonometer hears one beat per second. Calculate the speed with which the tuning fork is moved, if the speed of sound in air is 300 m/s.
