SPH3U: Module 8 Consolidation: Vibrations & Waves 1. A tuning fork produces a signal of 530 Hz. What frequency is: a. two octaves below this frequency? Hz. 2. Certain pipe organs can act like ai... r columns that are open at both ends. If the speed of sound is 343 m/s, how long must a pipe be to produce a frequency of 25 Hz (the lower hearing range of most adults)? 3. The "standard" note (A4 = 440 Hz) on a harp has a string length of 75 cm. How long would the same string have to be to produce middle C (261.6 Hz)? 4. An air column closed at one end, with a length of 25.3 cm, resonates in the first overtone. If the frequency of the sound wave is 1024 Hz, find the air temperature inside the column. [Show More]
