Science Question on Propagation of Sound
The frequency of a source of sound is 100 Hz. How many times does it vibrate in a minute?
Answer
Frequency is calculated as the number of oscillations divided by the total time:
Frequency = Total timeNumber of oscillations
The number of oscillations is determined by multiplying the frequency by the total time:
Number of oscillations=Frequency × Total time
In the given scenario:
Frequency of sound = 100 Hz
Total time = 1 minute (1 minute = 60 seconds)
Therefore, the number of oscillations or vibrations is calculated as:
Number of oscillations=100×60=6000
Hence, the source undergoes 6000 vibrations in a minute, generating a frequency of 100 Hz.
