Question

Your answer is partially correct. Try again. 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 = (3 times 10-5 V/m) sin[(5 times 1014 rad/s)t] E2 = (6 times 10-6 V/m) sin[(5 times 1014 rad/s)t + 45 degree] E3 = (6 times 10-6 V/m) sin[(5 times 1014 rad/s)t - 45 degree] E = ( mu V/m) sin [( times 1014 rad/s)t + degree] Click if you would like to Show Work for this question: Open Show Work

Explanation / Answer

Resultant electric field= E1+E2+E3= (3 x 10^(-5) + 2 x 6 x 10^(-6) x cos(45) ) x sin(5 x 10^14 t) + 6 x 10^(-6) x (sin(45)+sin(-45)) ) x cos(5 x 10^14 t)

= 38.485 (uV/m) sin(5 x 10^14 (rad/s) t+ 0 degree
