Question

Two waves are given below, interferes each other
what is the resultant wave and its amplitude?

Answer 1

\[\psi 1 =20Cos(5x+25t) \]
\[\psi 2 =20Cos(5x+25t+ \Pi/3)\]

Answer 2

Are the two waves travelling in the same direction?

Answer 3

information given in the question buddy,,,, i guess Pi /3 is the angel

Answer 4

\(\pi\)/3 is phase difference.

Answer 5

yeah same, phase difference between waves..

Answer 6

resultant wave?

Answer 7

resultant wave = \(\psi =\psi 1 + \psi 2\)
\[\psi=20\sqrt{3} \cos (5x +25 + \frac{\pi}{6})\]

Answer 8

so amplitude seems to be 20\(\sqrt3\)

Answer 9

juss to add waves?

Answer 10

is it?

Answer 11

yep

Answer 12

Just add these vectors to get the resultant amplitude.

Answer 13

r u sure guys?

Answer 14

Yep.
