Facts About Resonance | Facts behind resonance | resonance in history
# The remarkable phenomenon of great important throughout Physics that occur when an oscillator is subjected to an external periodic force by an external agency. This phenomenon is called as 'resonance '.
# When frequency of the applied force is equal to the natural frequency of an oscillator, it oscillates with maximum amplitude.
# As the natural frequency of the oscillator differs more and more from the forcing frequency, the response become less, so that the amplitude and energy of oscillation become less.
# The word resonance comes from Latin and means to "resound" - to sound out together with a loud sound. Resonance is a common cause of sound production in musical instruments. ... These impinging sound waves produced by the tuning fork force air inside of the resonance tube to vibrate at the same frequency.

# Resonance phenomenon occur widely in natural and in technological application :
- Emission and absorption of light
- lasers
- tuning of radio and television sets
- mobile phones
- microwave communication
- machine, building and bridge design
-musical instruments
-medicine -nuclear magnetic resonance
-X- rays
-Hearing
# Magnetic Resonance Imaging (MRI) is a type of scan uses magnetism to build up a picture of the inside of the body.
# 1) mechanical resonance : A child's swing has a natural frequency of its own. If the swing is subjected to a pushing force of frequency equal to the natural frequency of the swing, it is into resonant oscillation of large amplitude with little effort.
2) Electrical resonance : The radio tuning circuit contains LC circuit . The frequency of circuit depends on the value of L and C. The radio circuit is tuned by changing the value of the capacitor. If the frequency of circuit becomes equal to the frequency of radio waves transmitted by the transmitter from the radio station, the responce of the circuit is more and the circuit accepts that single, so that radio program is heard.
# Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies).
The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter, acoustic resonance can occur at frequencies outside the range of human hearing.

What are the 3 conditions for resonance?
The conditions to produce resonance in an object are: The object must have a minimum of one natural frequency of vibration. The object must be driven by an external force of vibration. The frequency of the external vibrating force must be similar to the object's natural frequency of vibration.
What does resonance depend on?
Resonance, An object free to vibrate tends to do so at a specific rate called the object's natural, or resonant, frequency. (This frequency depends on the size, shape, and composition of the object.)
What is resonance and what happens in it?
Resonance is a phenomenon that occurs when the matching vibrations of another object increase the amplitude of an object's oscillations.
What are the characteristics of resonance?
The main characteristic features of resonance are: (i) Resonance involves only the displacement of electrons over the same atomic nuclei. (ii) Resonance occurs only when all the atoms lie in the same plane. (iii) The resonating structures must have the same number of paired and unpaired electrons.
How many types of resonance are there?
Resonances are of five types they are Mechanical, Acoustic, Electrical, Optical, Orbital resonance.
