Three electromagnetic waves arrive at a point from the same direction. they are polarized parallel to an x axis, and their electric fields at the point are e1 = a sin(ωt) for wave 1, e2 = b sin(ωt + φ2) for wave 2, and e3 = c sin(ωt + φ3) for wave 3. here t is time. the constants are a = 3.0 µv/m, b = 4.0 µv/m, c = 5.0 µv/m, ω = 7.0 × 106 rad/s, φ2 = π/4, and φ3 = π/2. what is the amplitude (in µv/m) of the electric field that results from the interference of the three waves?
