Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the physical principle?Amplification of vibrations when driving frequency matches natural frequency
2. What is the determining factors?Size, shape, and material composition of the acoustic system
3. How does acoustic resonance help musical instruments sound better?Instruments like violins, flutes, and drums are built so their parts resonate at specific frequencies, which makes their sound louder and richer.
4. Why do some buildings or rooms sound strange at certain pitches?Buildings have their own natural frequencies, so when a sound matches one of those, the building can vibrate and change how the sound echoes inside.

Natural Frequency: The inherent frequency at which a system oscillates when disturbed and left to vibrate freely.
Amplitude: The maximum displacement or extent of oscillation, vibration, or wave.
Harmonics: Frequencies that are integer multiples of a fundamental frequency, representing higher modes of vibration.
Damping: The dissipation of energy in an oscillating system, typically due to friction or resistance.
