Order the sounds made by these sources from highest to lowest pitch.
Which instrument, a cello or a violin, produces a higher-pitched sound? Explain your answer.
The violin produces a higher-pitched sound than the cello. This is because the violin is smaller and has shorter, thinner strings than a cello. Shorter and thinner strings vibrate at a higher frequency, which results in a higher pitch.
Would these two waves produce a standing wave?
The singing of an opera singer caused a drinking glass to shatter. Explain this using what you know about resonance.
Resonance occurs when the frequency of the sound waves produced by the singer matches the natural frequency of the glass. This causes the glass to vibrate with increasing amplitude. When these vibrations become powerful enough, the glass cannot withstand the stress and shatters.
