Consider two waves, which are given by y₁(x, t)=A (k x- t) and y₂(x, t)= 3 A (k x- t) , where k is the wave number and is the angular frequency. The amplitude of the resultant waveform obtained by the superposition of the two waves is A_s and its phase difference with y₁ is _s . What are A_s and _s ?

Options

  1. AA_s=2 A and _s= 3
