Question #4095f

Answer 1

I got `600` waves per second.

Explanation:

We need to use the frequency equation here, which is

`f=v/lambda`

`v` is the velocity of the wave in `m"/"s`

`lambda` is the wavelength in metres

`lambda=50cm=0.5m`

`:.f=(300)/(0.5)=600`

So, its frequency will be `600` waves per second.

That's a very fast wave as well compared to its wavelength!
