Question

I have another question, but please explain in more details. I do not have a good background, so even though you think it is not complicated, but actually I do not have the basic equation that I must use and the details. Therefore, I do not know how to solve this problem.

Answer 1

this is my question

Answer 2

Excuse me IrishBoy123 did you answer my question, I did not find the answer

Answer 3

so we're doing another fourier transform

but the \(\sqrt{2 \pi}\)'s cancel out

and its in the limit \(\bar k _x - \delta \lt k_x \lt \bar k _x + \delta \)

can you process that?!

Answer 4

Answer 5

so it's
\[\huge \Psi(x,0) = \int_{\bar k _x - \delta }^{ \bar k _x + \delta} \ e^{i \ k_x \ x} \ dk_x\]

Answer 6

could you explain in more details?

I do not know if you gave me the last result or not
