Three simple harmonic waves , identical in frequency `n` and amplitude `A` moving in the same direction are superimposed in air in such a way , that the first , second and the third wave have the phase angles `phi , phi + ( pi//2) and (phi + pi)`, respectively at a given point `P` in the superposition    Then as the waves progress , the superposition will result in
