Question

Q. 6. 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

Answer:

Frequency = 500 vibrations/second. = (1/500) = 0.002 sec.

Explanation:

Frequency equals the number of waves that passes a given point per second or the number of oscillations of a vibrating body per second or number of cycles per second.

In this case, a mosquito vibrates its wings at an average rate of 500 vibrations per second. Therefore, the frequency of the sound is 500 Hz.

Time period of the wave is defined as the reciprocal of the frequency of the wave.

That is, T=
