Question

The time period of a source of sound is 0.01 s. How many times does it vibrate in a minute?

• A. 6000 times
  
• B. 600 times
  
• C. 1000 times
• D. 100 times

Answer 1

The correct option is A 6000 times


Time period of the sound source = 0.01 s (Given)
We know that,
Frequency = $\frac{1}{Timeperiod}$
= $\frac{1}{0.01}$
= 100 Hz
It means the source of sound vibrates 100 times in one second.
Therefore, the number of vibrations in 1 minute, i.e. in 60 seconds
= 100 x 60 = 6000 times.
