Respuesta :

The amplitude of a wave decreases gradually as the wave travels down a long, stretched string. The energy of the wave will also start decreasing

The energy of the wave is proportional to its amplitude

hence, a high amplitude  wave will indicates a high energy and a low amplitude wave will indicate low energy

So , as the amplitude of the wave decreases , it indicates the energy of the wave is also decreasing .
