In this problem, we have to find the resultant amplitude and phase constant by using the phased diagram.
00:07
So in this case, we need to find er and phi.
00:16
Now, let's begin with the phaser diagram.
00:19
So here we have y -axis.
00:23
This one, this is our y -axis, and then here we have x -axis.
00:29
So the first vector electric field vector is along this direction.
00:39
This is our e1 and it makes some angle with this x -axis.
00:44
The second electric field vector is downward so we can write it as this one.
00:53
So this is our e2.
00:55
Similarly we have the e3 as this one.
01:01
So this vector is e3.
