When a tuning fork (vibrating) is held close to ear, one hears a faint hum. The same (vibrating tuning fork) is held such that its stem is in contact with the table surface, then one hears a loud sound. Explain.

When a tuning fork vibrates will there be any overtones present ?

The stem of a vibrating tuning fork is pressed against a table top. Will it produce an audible sound ?

When the stem of a vibrating tuning fork is gently pressed on the surface of a table louder sound is heard. Why?

The stem of a vibrating tuning fork is pressed against a table top. Under what condition does it lead to resonance ?

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 g. 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.

Name the phenomenon that cause a loud sound when the stem of a vibration tuning fork is kept pressed on the surface of a table.

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 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.

The diagram above shows a wire stretched over a sonometer. Stems of two vibrating tuning forks A and B are touched to the wooden box of the sonometer. It is observed that the paper rider (a small piece of paper folded at the centre) present on the wire flies off when the stem of vibrating tuning fork B is touched to the wooden box but the paper just vibrates when the stem of vibrating tuning fork A is touched to the wooden box. Why does the paper rider fly off when the stem of tuning fork B is touched to the box ?

When a tuning fork is vibrated , another in the neighbourhood begins to vibrate . This is due to the phenomenon of

Using suitable diagram explain how sound wave propagates through air from a vibrating tuning fork?
