14.4 Sound Interference and Resonance

What is the term used to describe the phenomenon when a system is driven at its natural frequency?

• Damping

• Resonance

• Harmonics

• Overtones

Which term refers to the reduction of amplitude over time due to energy dissipation in a system?

• Beat frequency

• Resonance

• Damping

• Natural frequency

In the context of resonance, what is the natural frequency?

• The frequency at which a system naturally oscillates without external force

• The frequency at which energy dissipation is maximum

• The frequency at which damping is minimized

• The frequency at which overtones are produced

What is achieved when the finger moves with the natural frequency of the ball on the rubber band?

• Damping

• Resonance

• Overtones

• Harmonics

What is the phenomenon used by some headphones to cancel out outside noises?

• Resonance

• Constructive and destructive interference

• Echo

• Doppler effect

What is the result of the superposition of two waves with slightly different frequencies but the same amplitude?

• Echo

• Resonance

• Beats

• Doppler effect

How is the beat frequency calculated when two original wave frequencies are given as f1 and f2?

• fB = f1 + f2

• fB = f1 × f2

• fB = |f1 - f2|

• fB = f1 / f2

What is the result when a tuning fork causes resonance in a tube closed at one end?

• The air column vibrates at all frequencies.

• The air column vibrates at only certain natural frequencies.

• The air column does not vibrate at any frequency.

• The air column vibrates at a single frequency.

Where is the maximum air displacement found in a standing wave formed in a tube closed at one end?

• At the closed end of the tube.

• At the midpoint of the tube.

• At the open end of the tube.

• Throughout the entire tube.

What is the lowest resonant frequency in a system called?

• Harmonic

• Overtone

• Fundamental

• Antinode
