Question

What do you understand by the term resonance? Give two conditions for producing resonance.

Answer 1

Step 1:

Definition of resonance:

• It is defined as a phenomenon that occurs when the frequency of an applied external force equals the natural frequency of the body to which the force is applied, causing the body to readily absorb the vibrations and begin to vibrate with increased amplitude.

Step 2:

Two conditions for producing resonance:

• The natural frequency of the provided (given) body (non-vibrating body) must equal (or be an integral multiple of) the vibrating body’s frequency.
• The vibrating body must have enough force to cause the other body to vibrate as well.
