Question

The frequency of a wave is 200.0 Hz . Its velocity is 3.00 * 10 ^ 8 * m / s . What is the period of the wave?

Answer 1

In order to calculate the period of the wave, we can use the formula below:

`T=(1)/(f)`

So, to calculate the period, let's use the given frequency of 200 Hz:

`T=(1)/(200)=0.005=5\cdot10^(-3)\text{ s}`

Therefore the correct option is A.
