<p><strong class="ql-font-monospace">Wavelength </strong><span class="ql-font-monospace">is the distance between similar points on two back-to-back waves. When measuring a wave, the wavelength is typically measured from the peak of a wave to the peak of the next wave.</span></p><p><br></p><p><span class="ql-font-monospace">Next figure shows the wavelength of one signal</span></p>

<p><span class="ql-font-monospace">Here is another sample with different signal.</span></p>

<p><span class="ql-font-monospace">As shown the previous figures, the wavelength is based on how long the signal would take to repeat itself "This is why signals are called waves", the wavelength is determined by another attribute for the signal which is called frequencies and the there is an inverse relation ships between the wavelength and the frequency of the signal where wavelength will be higher when the frequency of the signal getting lower.</span></p>
