The sound from a mosquito is produced when it vibrates its wings at an average rate of 500 vibrations per second. What is the time period of the vibration?

Soln:

The time period is defined as the time taken to complete one oscillation. It is also the inverse of frequency.

Time period = 1

Oscillation frequency

Oscillation frequency = 500 Hz

The time period of the vibration = 1/500 = 0.002 s
