- Amplitude of a wave is the maximum displacement of the particles of a medium from their mean positions during the propagation of a wave.
- Here, the maximum displacement of the particles during wave propagation is equal to the height of the crests, i.e., EN or the depth of the troughs, i.e., MC.
- So, EN and MC are the amplitudes of the wave.
- The measure of EN is 1 mm.
- Hence, the amplitude of the wave is 1 mm.
- Note : I haven't considered -1 mm because amplitude cannot be negative.
Hope you could get an idea from here.
Doubt clarification - use comment section.
