Fairly easy, just add the two waves using superposition. ϕ ′ = 2 ϕ = 2 A 0 r s i n ( k r − ω t) for the resulting wave (the prime denotes superposition) Using I = h ( A 0 / r) 2 we see that I ′ = I × ( 2 A 0 / A 0) 2 = 4 I. Therefore the intensity has become four times larger. Share. Cite. Improve this answer.
