What does it mean when we say that two functions are orthogonal (the physical meaning, not the mathematical one)? I tried to search for the physical meaning and from what I read, it means that the two states are mutually exclusive. Can anyone elaborate more on this?
Why do we impose orthogonality condition in many of the problems like infinite square well, harmonic oscillator etc?
