Wave function and Relationship with Intensity

Postby Angie Sun 2E » Tue Oct 31, 2023 9:59 am

I know that the wave function squared is equal to the probability density of finding an electron in a certain region of the atom. Also, the amplitude squared of a wave is the intensity of the light. I was wondering if there is any relationship between the wavefunction squared and amplitude squared? For instance, would the wavefunction squared also equal to intensity? Thank you!

The square of the wave function and the square of the amplitude have their own distinct meanings in their respective contexts. The square of the wave function relates to the probability density of finding a particle in a specific position or quantum state, while the square of the amplitude relates to the intensity of a classical wave. It is important to know that although the intensity of a wave is related to the square of the amplitude of the wave, this is a different concept from the probability of finding the particle described by a specific wave function. Hope this helped!
