Question

what is the wavelength of waves at the beach if they have a frequency of 0.3 Hz and they move at 7.1 m/s?

Answer 1

23.67 m

Step-by-step explanation:

We are given;

Frequency; f = 0.3 Hz

Speed; v = 7.1 m/s

Now, formula to get the wavelength is from the wave equation which is;

v = fλ

Where λ is wavelength

Making λ the subject, we have;

λ = v/f

λ = 7.1/0.3

λ = 23.67 m
