Also, explain about resonance and frequency and differentiate between them by giving an example for each of the phenomena. Note: Here, first explain about tuning fork, give a brief about its purpose and its construction. The index mechanism also means the tuning fork watches are characterised by a. When a vibrating tuning fork is placed on a table, a large sound is heard. But as a very brief introduction, the tuning fork watch is like no other battery driven watch, or mechanical for that matter: it is driven by a tuning fork vibrating at 300-720 times a second, depending on the model as a result, it doesn’t tick, but hummms. Similarly, a good example of a forced vibration is when we put an already vibrating tuning fork on the table and we hear a large sound.įinal answer is option A. Here, a good example of resonance is when we bang the tuning fork on the table and bring it closer to our ear the air around the fork starts to vibrate and then we can hear the sound. Resonance is a phenomenon in which a vibrating system forces another system which is around it to vibrate with greater amplitude at a given frequency whereas a forced vibration is a phenomenon in which an alternating force or motion of an object or a system is applied to a system of a mechanical nature, in forced vibration the force is repeatedly applied to a mechanical system. A resonator is a device which oscillates naturally at greater amplitudes at a given frequency, these frequencies are called resonant frequencies. It is a type of resonator and unlike other resonators it gives out a pure sound. It is a U-shaped device that is made up of metal. The mechanical system you will use is a large tuning fork, in which two.

Tuning fork as the name suggests is a device that is used for tuning musical instruments. French, Vibrations & Waves, (Norton 1971) The chapters on Free Vibrations. The tuning fork is soundless when it is in an ideal state and we bang the tuning fork on the table or on any solid surface and bring the tuning fork closer to our ear when we hear a sound. 2 The method used by both involves the periodic opening and closing of the electrical circuit by the vibrating forks. The vibration mechanism is simple, so it produces a sound with a single frequency well.
When the tuning fork is vibrated, the tuning fork repeatedly approaches and then moves away from each other. Hint: Sound happens when there is a to and fro motion of an object, when an object oscillates on its own then the sound happens. Basic motion of air molecules Tuning fork The tuning fork has a structure that combines the ends of two sticks.
