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

We have waves propagating in the air. First part asks for a traveling wave solution in the x direction , given a wave length 2pi and amplitude 3m. I have obtained u(x,t) = 3 cos ( x - 345t). The question then asks what happens if a wall is placed at x=0, what is the form of u(x,t) including the reflect wave and incident wave. Also to find the amplitude and phase of the reflect wave given u(0,t) = 0.

2. Relevant equations

z(x,t)=Asin(ks-vt)

3. The attempt at a solution

I have hit a wall. No idea how to proceed with the form of the equation. Once I get that, I am pretty sure I will manage to find the phase shift and amplitude.
