the sound from a mosquito is produced when it vibrates it's wings at an average rate of 500 vibration per second. what is the time period of the vibration ?
Answers
What is the time period of the vibration?
Solution 6:
Frequency = 500 vibrations/second.
= (1/500) = 0.002 sec.
Answer:
0.002 seconds
Explanation:
As per the the question the sound source is the mosquito.
the mosquito produces the sound with the help of its wings
as per the question the wings vibrate at the rate of 500 vibrations per second.
we have been asked to calculate the time period of vibration.
we know that that time period is the reciprocal of frequency of vibration
hence time period [T]=\frac{1}{frequency}frequency1
=\frac{1}{f}f1
=\frac{1}{500} second5001second
=0.002 second
hence the time period of the vibration of the wings of the mosquito is 0.002 second.
(OR)
Step-by-step 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=f1=5001=0.002second.
Hence, time period of the sound produced by the mosquito is 0.002 second.
