In quantum mechanics, why is a wave function not normalizable if it always has the same sign as its second derivative?

The normalization condition for a wave function in quantum mechanics requires that the integral of the squared magnitude of the wave function over all space is equal to 1. However, some wave functions may not satisfy this condition, making them non-normalizable.
A non-normalizable wave function does not have a finite total probability. This means that the probability of finding a particle described by this wave function is not well-defined and cannot be calculated.
Yes, in some cases, non-normalizable wave functions can still be used to describe physical systems. For example, in the case of free particles, non-normalizable wave functions can still be used to describe the spread of the wave function over all space.
Wave functions that are non-normalizable are typically those that exhibit infinite or unbounded behavior. This can occur in cases such as a particle in an infinite potential well or a wave function that describes a free particle with infinite momentum.
Wave functions that are non-normalizable cannot be used to make predictions about the probability of finding a particle in a specific state. In order to make accurate predictions, the wave function must be normalized. However, non-normalizable wave functions can still be used as mathematical tools for understanding the behavior of quantum systems.
