1.	What do you understand by the term resonance ? Give two conditions for producing resonance.
Answer» Resonance : “is a special case of forced vibrations. When the frequency of an externally applied periodic force on a body is equal to its natural frequency, the body readily begins to vibrate with an increased amplitude. This phenomenon is called resonance.” Two conditions of resonance : 1. The natural frequency of the given body (non-vibrating body) must be equal to (or its integral multiple) the frequency of the vibrating body. 2. The vibrating body must have sufficient force, so as to. set the other body into vibrations.
