    1. The time period of vibration can be calculated using the formula:

      Time Period = 1/Frequency

      Given:
      Frequency of mosquito’s wings = 500 vibrations per second

      Using the formula:
      Time Period = 1/(500 vibrations/second)
      Time Period = 0.002 seconds

      Therefore, the time period of the vibration of the mosquito’s wings is 0.002 seconds.
