A. 1.0 cm
Explanation
Wavelength refers to the length of a wave from one peak to the next,The wavelength is measured from peak to peak. Wavelength is directly related to the frequency of a given wave form
so
we need to find the distance from peak to peak
to do that, subtract the x components of the peaks , so
[tex]\begin{gathered} wavelength=\lambda=2.5\text{ cm-1.5 cm=1.0 cm} \\ \end{gathered}[/tex]
therefore, the answer i
A. 1.0 cm
