Class 11PhysicsOscillationsDifferent types of oscillations (Free, Damped, Forced Oscillation and Resonance)
MediumWhat is resonance? Give its example.
(N/A) Resonance is a phenomenon in which an external periodic force or a vibrating system causes another system to oscillate with a significantly larger amplitude when the frequency of the applied force matches the natural frequency of the system.
Example: Consider a child on a swing. $A$ swing has a specific natural frequency of oscillation. If the child (or someone pushing the swing) applies a force at regular intervals such that the frequency of the pushes matches the natural frequency of the swing,the amplitude of the oscillations increases significantly. This is a classic example of mechanical resonance.
