The discussion focuses on calculating the amplitude of the resultant wave from two identical waves with a known phase difference. The equations used are A1 = Ao(sin(wt + φ1)) and A2 = Ao(sin(wt + φ2)). By adding these two wave equations, one can determine the resultant amplitude based on the phase difference between the waves. This method is essential for understanding wave interference in physics.
