SUMMARY

Orthogonality in wavefunctions is established by demonstrating that the inner product of the two wavefunctions equals zero, without the necessity of normalization. Normalization, which scales wavefunctions to unit length, is not a prerequisite for proving orthogonality. The discussion highlights that orthogonal vectors in Euclidean 3-space are perpendicular, emphasizing that their magnitudes do not affect their orthogonal status. Normalized orthogonal vectors are referred to as orthonormal.

Homework Statement



If you want to show two wavefunctions are orthogonal, do you have to normalize the wavefunctions first then take the integral of the product and see if they're equal to 0?

The Attempt at a Solution


not really applicable. I just want a explanation.

Nope. Orthogonality just requires the inner product to be zero.

A good visualization (though not in Hilbert space): In Euclidean 3-space (where inner product is the dot product) orthogonal vectors are perpendicular. Normalization scales vectors to the unit length. Heres the point: two vectors are perpendicular (orthogonal) regardless of their magnitude.

Normalized, orthogonal vectors have a name too: orthonormal.
 
okay thank you for the help!
