Physics Review Question Unit: Waves Year: 1991 Question#: 45 Question: An opera singer's voice is able to break a thin crystal glass if the singer's voice and the glass have the same natural (1 ) frequency (2 ) speed (3 ) amplitude (4 ) wavelength What is this question really asking? Explanation by: Nathaniel W [ Return to question menu ] Answer 1 frequency CORRECT Correct, if you put energy into an object at its natural frequency, it will resonate and in the case of glass, will shatter the glass. return to top Answer 2 speed INCORRECT Only frequency relates to resonance, speed is not the correct answer. return to top Answer 3 amplitude INCORRECT Only frequency relates to resonance, not amplitude. return to top Answer 4 wavelength INCORRECT Only frequency relates to resonance, not wavelength. return to top What's this question really asking? What means of energy transformation does resonance use. return to top |
