(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two traveling sinusoidal waves are described by the wave functions

y1 = (5.00m) sin[pie(4.00x - 1 200t)]

y2 = (5.00m) sin[pie(4.00x - 1 200t -0.250y)]

where x, y1, and y2 are in meters and t is in seconds.

(a) What s the amplitude of the resultant wave?

(b) What is the frequency of the resultant wave?

2. Relevant equations

y = (2Acos Phi/2) sin(kx- wt + Phi/2)

3. The attempt at a solution

The two waves are out of phase by 0.250

therefore A = (2A cos Phi/2)

I get the Amplitude to be 9.99 or 10m

from 2 (5.00m) .25/2

Do I need to do more for this? I know the answer but can't get there

Thanks,

Kevin
