Question

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?

Answer 1

The time required to complete one oscillation is known as the time period. It is given by the inverse of the frequency.

Time period  = `1/"Frequency of oscillation"`

Frequency of oscillations = 500 Hz

Time period  = `1/500` = 0.002 s

So, the time period of vibration = 0.002 s.
