Answer:
Natural frequency
Explanation:
Natural frequency is defined as the requency at which a system performs oscillation without any driving force.
All the objects produces sounds when they vibrates. Natural frequency occurs when an object is allowed to vibrate through the molecular wavelength ofanother body and the vibration produces sound wave.
Hence, the correct answer is natural frequency.
Answer:
Interference.
Explanation:
Interference occurs when a body’s molecular wavelength sends vibrations to another body, resulting in the production of another sound wave
Hope this is correct. Have a great day.
