The frequency of a source of sound is 100 Hz. How many times does it vibrate in a minute ?
Solution:
No. of vibrations produced in 1 s = 100
$\therefore$ No. of vibrations produced in 1 minute i.e.,
60 seconds = 100 × 60 = 6000.
Thus, the source of sound vibrates 6000 times in a minute.
No. of vibrations produced in 1 s = 100
$\therefore$ No. of vibrations produced in 1 minute i.e.,
60 seconds = 100 × 60 = 6000.
Thus, the source of sound vibrates 6000 times in a minute.
