Three electromagnetic waves travel through a point P along the x axis. They are polarized parallel to the y axis, with the following variations in their amplitudes. What is the phase angle of their resultant at P?
E1 = (3 × 10-5 V/m) sin[(2× 1014 rad/s)t]
E2 = (5 × 10-6 V/m) sin[(2× 1014 rad/s)t + 45°]
E3 = (5 × 10-6 V/m) sin[(2× 1014 rad/s)t - 45°]
E = (μV/m)sin[( × 1014 rad/s)t + °]
