प्रश्न
The frequency of a source of sound is 100 Hz. How many times does it vibrate in a minute?
उत्तर
Frequency is defined as the number of oscillations per second. It is given by the relation:
`"Frequency"="Number of oscillations"/"Total time"`
Number of oscillations = Frequency × Total time
Given, Frequency of sound = 100 Hz
Total time = 1 min = 60 s
Number of oscillations/Vibrations = 100 × 60 = 6000
Hence, the source vibrates 6000 times in a minute, producing a frequency of 100 Hz.
