Hi friends, the resulted amplitude of two waves is given by e0 square is equal to e01 square plus e02 squared plus 2 e01 into e02 into cause of alpha 2 minus alpha 1.

Here alpha 2 and alpha 1 is zai 2 and zai 1 so you can write e0 squared to be a not one square plus a not two square plus two e not one into e not two cause of zy two minus x i one see equation one now substituting the value e not you will get root of a not one is given six e not two is given eight and zy two minus zy one is given ninety degree so it is to be 10 unit.

Now the angle by which there will be shift in resultant.

So 10 of alpha will be e01, sine of alpha 1, e02, sine of alpha 2, xan of alpha 2 divided by a01, cause of alpha 1, e02, cos of alpha 2.

Substituting the value 6 into sine of 0, 8, into sine of pi by 2, 6 cost of 0, 8 into cost of pi by 2...
