The waves going to the right from antenna 1 and 2 are D_(1,R)=A sin(kx-ωt) D_(2,R)= A sin〖(k(x-L)-ωt+ϕ_2,0)〗 Write down the sum of the two waves 〖D_(net, R)= D〗_(1,R)+D_(2,R )and the phase difference Δϕ_R= ϕ_2- ϕ_1 between the two waves. On section 17.6 of the book where you will find the trigonometric identity:
