Chapter 35, Problem 33P

GO 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 X 10¹⁴ rad/s)t]

E₂ = (5.00 μV/m) sin[(2.0 X 10¹⁴ rad/s)t + 45.0°]

E₃ = (5, 00 μV/m) sin[(2.0 X 10¹⁴ rad/s) t − 45.0°]
