The electric fields of two harmonic waves of angular frequency w, and we are
given by E₁ E₁,0cos (k₁y + w₁t)i and E2 = E2,0cos (k₁y-w₂t)î. Find (a) the
instantaneous Poynting vector for the resultant wave motion and (b) the time-average
Poynting vector. If the direction of propagation of the second wave is reversed, find (c)
the instantaneous Poynting vector for the resultant wave motion and (d) the time -average
Poynting vector.
