Question

The frequency of a source of sound is 100 Hz. How many times does it vibrate in a minute?

Answer

Given:

  • Frequency (\nu) = 100 \text{ Hz} (This means 100 vibrations per second)

  • Time (t) = 1 \text{ minute} = 60 \text{ seconds}

Calculation:

\text{Total Vibrations} = \text{Frequency} \times \text{Time}
\text{Total Vibrations} = 100 \times 60
\text{Total Vibrations} = 6000

Answer:
The source vibrates 6000 times in a minute.
