Hello I am confused about the concept of particle or electron in the box can someone kindly explain?

"Electron in a box" essentially means that an electron has a certain energy which goes hand in hand with a wavelength in an energy state thus the electron is limited in its energy level since the space around the electron in limited so that is why we call it a "box"
