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.

i'm thinking more like energy

i guess it’s a and b
