Anote on a piano vibrates 282 times per second. what is the period of the wave?

The period of the wave is 3.54 ms.

Explanation:

In wave motion, period is defined as the time taken to complete a single cycle. In other words, period can also be termed as inversely proportional to frequency.

As frequency states the number of times a cycle is getting repeated in a given time interval. So from this we can find it for a single cycle. Thus,

As the frequency is given as 282 , then the time period will be

So, the period of the wave is 3.54 ms.

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure
