Three electromagnetic waves travel through a certain point P along an x axis. They are polarized parallel to a y axis, with the following variations in their amplitudes. Find their resultant at P
E1 = (10.0 μV/m) sin[(2.0×10^14 rad/s) t ]
E2 = (5.00 μV/m) sin[(2.0×10^14 rad/s) t+45.0∘]
E3 = (5.00 μV/m) sin[(2.0×10^14 rad/s)t−45.0∘]
