Respuesta :

the energy of the wave decreases gradually

Answer:

Explanation:

  The energy of the wave its determined by the mass of the fuid of the wave and the speed. The amount of motion equation P= m.v

  So according to the impulse and amount of motion theorem (ΔP= mvₙ- mv₀).

  If the wave is acted upon by an external dumping force, the wave its going to decrease his energy because the reduction of the speed and the mass.
