Question

a wave has a frequency of 5 HZ and a speed of 25 m/s. what is the wavelength of a wave?

Answer 1

Wave speed = frequency * wavelength

We need to rearrange this equation because we are finding the wavelength :

Wavelength = wave speed / frequency

To rearrange it, I just divided it by frequency so that wavelength was the subject.

Now, input these numbers into this equation :
Wavelength = wave speed / frequency
Wavelength = 25 / 5
Wavelength = 5m

Answer 2

I believe the the wavelenth of a wave is 5m.
Hope this helps!
