# Electron Wavelength in Infinite Potential Well

I'm a little confused about the electron wavelength in an infinite potential well.

It is my understanding that the maximum wavelength that the electron can achieve is 2 times the length of the potential well.

As the eigenvalue increases, does the wavelength change?

I believe that the wavelength will be λ = 2a/n, with a being the length of the infinite potential well and n being the quantum number, but I'm not completely sure.

Any help is appreciated.

that all looks fine.
