Question
The total number of compressions and rarefactions produced per second in a sound wave is 1000. The frequency of the sound wave is __________.
Solution
The total number of compressions and rarefactions produced per second in a sound wave is 1000. The frequency of the sound wave is 500 Hz (One compression and rarefaction together makes a cycle of sound wave).
