<p><strong class="ql-font-monospace">Amplitude </strong><span class="ql-font-monospace">is the height, force, or power of the wave. electromagnetic waves transmitted like a signal with certain power that can be represented a shown in the below figure.</span></p><p><br></p><p><span class="ql-font-monospace">When the wave reach the maximum value "peak" the value at this peak is called the wave amplitude</span></p>

<p><span class="ql-font-monospace">Next figure compares two signal with same frequencies but different amplitudes.</span></p>

<p><span class="ql-font-monospace">In the previous diagram we can see the that red wave has a higher amplitude comparing to the blue, this value indicates that red wave has more power than the blue one.</span></p>
