If the Q factor goes higher, the energy loss goes lower. It also characterizes a resonator's bandwidth relative to its center frequency. How under-damped an oscillator or resonator will be described by the Q factor. Q factor is such a parameter in Physics which is dimensionless. The quality of Resonance is determined by the Q factor. Apart from Acoustic musical instruments, Acoustic Resonance is an important thing for hearing too. Here, g denotes the acceleration due to gravity, and L denotes the length.Īcoustic resonance is an important thing for musical instruments because resonators are used in mostly acoustic musical instruments such as the strings and the body of a violin, and the length of a tube in a flute. Any time the resonance frequency of this circuit matches the frequency of any station or channel, that channel we receive. When we rotate the 'nab' of the radio, it is virtually changing the resonance frequency of this tuned circuit. Radio and Television - There is a tuned circuit inside the radio and the TV which helps to hear or see a channel. On the contrary, if it is pushed on another frequency without taking into consideration as mentioned above, its effect can be very low, zero or negative. That is, every time the hammock makes more angle than its mean position. Swing - When pushing the swing, keep in mind that the push should be given at the same interval which is the natural rotation of the swing, and then the dimension of that swing increases only. Mostly vibrating objects have multiple Resonant frequencies.Įxamples of Resonance - Some examples of Resonance are as follows: It is easy to vibrate an object at its natural frequency, but it is hard to vibrate an object at the other frequency.Ī vibrating object chooses only that frequency from complex excitation which is equal to its frequency. Some implications of the resonant frequency are as follows: ![]() (Note - In a system, Friction, Viscosity, and Resistance are some elements which are responsible for the energy loss.) ![]() The elements which can destroy the energy of the system must be least. There are three things needed for the incident of Resonance, and they are:Īn Object or a System which has a natural frequency.ĭriving Force whose frequency is the same as the natural frequency of a system. Resonance can happen with Mechanical, Sound, and Electromagnetic wave functions. The incident of resonance is associated with all kinds of vibrations or waves. The frequency on which oscillation of the highest frequency is found is called Resonant Frequency. In Physics, there are a lot of systems that have a nature to oscillate with larger amplitudes on such frequency, and that condition is called Resonance.
