comment Are my results realistic or is there an error somewhere?
Very good answer and comments. I worked long to understand my results because it didn't look right that the wave changed direction when looking at the depth and the x-axis for the sound. I think this was an interesting exercise that also had meaningful physical interpretation.

Thank you very much. I suppose it is ok to state that the sound wave appears to change direction several times from looking at the graph. This was puzzling me and I'm glad for the link @NickThompson thanks again!

comment Is my matlab code solving the problem?
Thank you for the comment. I wrote the derivate like this (-272.9057*0.7528/1000)*exp(-Z(1)*0.7528/1000)) + 17.3368/1000 Do you think it's wrong and that it has a sign error? I'm not sure what that should be. Please inform me what can be the mistake.

I have written my derivative like this (-272.9057*0.7528/1000)*exp(-Z(1)*0.7528/1000)) + 17.3368/1000 is it incorrect? I'm sorry that I don't understand what can be wrong.

Thank you for the information. But I don't fully understand how you write the derivative. Should it not be differentiated term by term?

comment Is there a good way to solve for z the equation $e^{i\pi} = e^{z\ln2} + e^{z\ln3}$?
I reward yo for clarity and find explaining the difficulty. I'm going to study if a transform can rewrite the equation as a solvable equation.

Can you please elaborate how we make it two equations?
