What are the highest and lowest frequencies heard by a listener standing a few metres away, if the speed of sound in air is 340 m s–1?
A short string will usually oscillate with smaller amplitude than a longer string. Explain the consequence for the relative loudness of different frequencies played by a string instrument if this was not the case. Additionally, a whistle producing a sound at 1 KHz is whirled in a horizontal circle at a speed of 18 m […]
