Detailed explanation-1: -Since the incoming sound waves share the same natural frequency as the second tuning fork, the tuning fork easily begins vibrating at its natural frequency. This is an example of resonance-when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion.

Detailed explanation-2: -Resonance can occur only if external force is applied at same frequency as that of natural frequency, hence it is forced vibration.

Detailed explanation-3: -An example of acoustical resonance is the vibration induced in a violin or piano string of a given pitch when a musical note of the same pitch is sung or played nearby. The concept of resonance has been extended by analogy to certain mechanical and electrical phenomena.
