De Broglie Wavelength & Classical EM Wavelength Comparison

Click For Summary
SUMMARY

The discussion centers on the conditions under which a particle's de Broglie wavelength equals the classical electromagnetic (EM) wavelength. It concludes that while a particle and an EM wave can have matching wavelengths, this comparison lacks significance, as they are fundamentally different entities. The de Broglie wavelength is deemed obsolete in modern physics, having been superseded by more comprehensive quantum mechanics concepts.

Under what condition would particle de Broglie wavelength be equal to the classical EM wavelength?
 
Physics news on Phys.org
A particle is different from an EM wave and so it doesn't have an EM wavelength. So there is no special value to call "the classical EM wavelength". And EM waves can have any wavelength, so you can find some EM wave with a wavelength equal to the de Broglie wavelength of some particle but there is no meaning behind it. Its like picking an apple and asking whether there is any car with the same color as this apple. Yes, there is. But...what's the point?
Also the de Broglie wavelength is something that is no longer used. Its an obsolete concept. It was there when people still didn't completely understand quantum mechanics.
