1. The problem statement, all variables and given/known data A wave in quantum mechanics is represented by Aei(kx-[tex]\omega[/tex]t). Show that a standing wave looks like 2iAe-i[tex]\omega[/tex]tsin(kx) by subtracting two waves moving in opposite directions. (Hint: make the k negative in one of the waves) 2. Relevant equations As far as I know, the 2 equations in the problem 3. The attempt at a solution Honestly, I have no idea where to start. Any help would be greatly appreciated.
