Question

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

Answer 1

Answer:

6,000 times

Explanation:

Frequency = No. of vibrations per second

So, a frequency of 100 Hz would mean the object vibrates 100 times in a second.

To find the no. of times it vibrates in a minute,

Vibrations in 1 minute = Vibrations in 1 second * 60

⇒ Vibrations in 1 minute = 100 * 60

= 6000 Vibrations

Hence, the object vibrates 6,000 times in 1 minute.
