Question

This wave, in total, is 30m. What is it's wavelength? *
Your answer

Answer 1

Looking at the wave diagram

Its wavelength 3full wavelength which total to 30m...

So

3y = 30

y= 30/3

y=10meters

So a single wavelength is 10m.

Hope it helps

Answer 2

wavelength = d / number of Oscillation

this implies that wavelength = 30/3= 10

number of wavelengths = 10
