Explain what physicists mean when they say that the de broglie wavelength relates to the probability distribution wave function.

Because it unites particle and wave nature.

Explanation:

De Broglie wavelength can be defined as the,

Here, h is planks constant, m is the mass of electron, v is the velocity of electron.

Since the de Broglie wavelength can behave like the photon wavelength with respect to the  momentum

It unites particles and waves nature ,so De Broglie wavelengths is probability waves associated with the wave function according to physicists.

wavelength variability is the right one

answer///terminator or twilight zone;
