S(1) and S(2) are two sources of light ...

`S_(1)` and `S_(2)` are two sources of light which produce individually disturbance at point `P` given by `E_(1)=3sin omegat,E_(2)=4 cos omegat.` Assume `vec(E_(1))&vecE_(2)` to along the same line, find the resultant after their superposition.

Text Solution
