प्रश्न
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?

उत्तर
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.
