The natural frequency is the frequency at which a system would oscillate if there were no driving and no damping force. ... The phenomenon of driving a system with a frequency equal to its natural frequency is called resonance. A system being driven at its natural frequency is said to resonate.

1. Natural frequency:
The natural frequency is the rate at whichan
object vibrate when it is not Disturbed by an
outside force.
Every body has its ownnatural frequency
Resonance:
When the driving frequency is equal to the
one of the natural frequency of the system
then the amplitude response of the systemis
maximum.This phenomenon is called
Resonance.

2. • Resonance:
• Resonance is an event
which occurs when a
system is provided with
the external periodic
force which has the
natural frequency.
• The amplitude of the
supplied force determine
the amplitude of the
Resonance.
• Natural frequency:
• Natural frequency is a
property of a system.
• Every object has its own
natural frequency.depend
upon the:
• Shape, elasticity,length,
material,and other factors
of the objects.

3. Explanation of Resonances:
Resonance is when the frequencies of forced
vibration on an object matches the objects natural
frequency causing a dramatic increase in amplitude....
.. some examples of Resonances including:
A vibrating metal rod,this force the air column inside
the rod to vibrate at the same frequencies.

4. Examples of
Resonances
:
These are the
following examples
of Resonances:
