Consider N coherent sources described as follows E1 E0sin (wt ), E2 E0sin (wt 2 ), E3 E0sin (wt 3 ) EN E0 sin (wt (N) Find the minimum value of for which ER E1 E2 E3 EN is zero

Question: Consider N coherent sources described as follows: E1 = E0sin (wt + ), E2 = E0sin (wt + 2 ), E3 = E0sin (wt +

Consider N coherent sources described as follows: E1 = E0sin (wt + ǿ), E2 = E0sin (wt + 2 ǿ), E3 = E0sin (wt + 3 ǿ). . . EN = E0 sin (wt (Nǿ). Find the minimum value of ǿ for which ER = E1 + E2 + E3 + . . . + EN is zero.
