**Two sinusoidal waves, identical except for phase, travel in the same direction along a string, producing the net wave**

y(x,t)=(5.5

y(x,t)=(5.5

*mm*)sin(12.0x -2.0*s-1** t+0.390 rad),**A. with x in meters and t in seconds. What is the wavelength λ of the two waves?**

B. What is the phase difference between them?

C. What is their amplitude ym?

B. What is the phase difference between them?

C. What is their amplitude ym?

I know A is .524 m but I am not too sure why. Other than that, I don't really know what I am doing. My general issue here is that I do not fully understand the form of the equation. Any information on what the different terms in the equation do would be helpful.

I got the answer for A from (2pi)/12 btw. The 12 was the coefficient of the first term, but again I don't really understand what is happening here.
