Is De Broglie Wave a Concrete Wave? Yes, let's talk about de Broglie's formula. If not, let's talk about the concept. Give some examples.

De Broglie wave is not a kind of visible and tangible wave, but a kind of material wave, that is, any object with momentum will exist correspondingly. De Broglie's formula is:

wavelength = Planck constant/momentum, that is, λ=h/p

, which shows that any object is actually a wave and can produce wave effect. But we can't directly perceive the de Broglie wave. For example, a moving electron is a de Broglie wave, which can be diffracted and interfered like a water wave. Therefore, electrons can produce interference images like water waves after passing through the double slits, that is, after the double slits, electrons are likely to appear in some areas and cannot be found in some areas. Because Planck's constant is very small and the momentum of macroscopic objects is very large, the wavelength is too small to have an observable effect. Therefore, generally only microscopic objects can show the wave effect.
