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. Tuning forks are a form of mechanical energy that uses the physical molecules to travel through a medium form the source to the receiver. Forced vibration: Most objects, including musical. As the water level is allowed to fall, a loud sound is heard for. There are two parts are composed of tuning fork resonance, which are the forced vibration and resonance. When a vibrating tuning fork is placed on a table, a large sound is heard. A vibrating tuning fork is held over a water column with one end closed and the other open. 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. The purity of the emitted tone is intimately related to the decay of the vibration amplitude. A resonator is a device which oscillates naturally at greater amplitudes at a given frequency, these frequencies are called resonant frequencies. The actual mechanical vibrations of these instruments create acoustic waves that we hear as sound. The tuning fork structure has an in-phase vibration mode and anti-phase vibration mode. the frequency of the energy harvester can be easily and quickly adjusted to the same frequency as the environmental vibration. It is a type of resonator and unlike other resonators it gives out a pure sound. The contact method is realized by mechanical means. It is a U-shaped device that is made up of metal. Tuning fork as the name suggests is a device that is used for tuning musical instruments. 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. 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.
