The distance between $5$ wave troughs is $64$ cm. Determine the wavelenght.
I thought that
$$5 \lambda = 64$$ $$\lambda = 12.8$$
However, the correct answer seems $16$, why?
Regards!

There are only $4$ wavelengths. The distance between TWO wave troughs is one wavelength. If you plot several periods, it is the distance between $5$ and $1$, $5-1=4$
