Answer 1

Answer:

Why is the de Broglie wave equation meaningful only for submicroscopic particles, such as atoms and electrons but not for larger everyday objects? It's only meaningful for submicroscopic particles because we can't see everyday object act like a wave because the wavelength is too small compared to the object.

Answer 2

The wavelengths of macroscopic particles are too tiny to be detected or to have any discernible influence on their behaviour, thats why de Broglie's connection does not apply to macroscopic particles.

• For subatomic particles like electrons and protons, whose wavelengths are substantial and quantifiable, De Broglie's connection, which stipulates that every particle has a wavelength associated with it, has significance.
• The de Broglie wavelength equation provides a particle's wavelength:  
• λ = h/p

       where

       λ is the wavelength

       h is Planck's constant

       p is the momentum of the particle.

• As the momenta of subatomic particles like electrons and protons are substantial and observable, investigations may compute and measure the wavelengths of these particles.
• These wavelengths are significant because they have the potential to display wave-like phenomena, such as diffraction and interference, which is not consistent with classical physics.
• On the other hand, because of their huge momenta, macroscopic particles like a baseball or a vehicle have insignificant and incredibly minuscule associated wavelengths.
• As the wavelengths of macroscopic objects are far shorter than their sizes, any wave-like behaviour is almost undetectable and has no influence on their behaviour.
• Due to the fact that the related wavelengths of macroscopic particles are too tiny to be detected or to have any discernible influence on their behaviour, de Broglie's connection does not apply to them.
