Which of the following is an accurate statement?
A)A system like a vibrating string has only one possible frequency.
B)In order for a singer to break a wine glass by singing,she must adjust the amplitude of the sound she makes so that it is exactly equal to the amplitude of vibration of the wine glass.
C)The fundamental frequency of a system is the name given to the highest possible frequency at which the system will naturally vibrate.
D)The sound in an organ pipe can vibrate at an infinite number of frequencies.

Question

Quizplus · Accepted Answer

The sound in an organ pipe can vibrate at an infinite number of frequencies due to the presence of multiple harmonics. A vibrating string or any simple harmonic oscillator has multiple possible frequencies, not just one. Adjusting the amplitude of a singer's voice to match that of a wine glass would require precise tuning, but it is not necessary to achieve resonance and break the glass. The fundamental frequency is the first harmonic, not the highest possible frequency.
