Why do you say that electrons have wave properties?

Answer 1

It was not just DeBroglie that reached that conclusion, others contributed to that theory, like Einstein, Bohr, Heisenberg and Schrödinger. What DeBroglie did was to establish that matter in general has that duality, but it can only be observed in microscopic particles, like electrons, because they are so small and travelling so fast that the wave nature is apparent. His formula can be used for any object, but only at the microscopic level is where we can observe the wave properties of a particle.

Answer 2

DeBroglie did not "discover" his hypothesis in the way that it was just standing there, waiting to be discovered to the first person who wandered around.

He noted that Einstein had said that waves can act like particles, and speculated that particles could thus act like waves. He worked out the mathematics in a self-consistent manner in his doctoral thesis. Within a year of the publication of his thesis, experimental results showed he was basically correct in his hypothesis.

Answer 3

Electron diffraction refers to the wave nature found in electrons. Louis de Broglie explained electron diffraction through his de Broglie hypothesis, which predicted that particles should also behave as waves.

Answer 4

According to de Broglie's wave-particle duality, an electron acts as both a particle and a wave. Electrons can be observed to act as particles when they are emitted in discrete portions from substances. Electrons act as waves when they are sent through a very narrow slit and form a diffraction grating.

Answer 5

When a beam of electrons are bounced off a crystal, their scatter pattern was identical as that of x-rays scattering from such a crystal. The wavelength of the scatter patter matched perfectly with the DeBroglie Wavelength. This experiment was done over 85 years ago. Your question is akin to, "Is there any experimental evidence that proves we can send video signals through the air?"

More recently, individual electrons were sent around a filament into a detector. When the sum of each individual electron striking the detector was made, an un-mistakeable interference pattern emerged.

Answer 6

De Broglie suggested that, like light, electrons could act as both particles and waves. De Broglie's showed electron beams could be diffracted or bent as they passed through a slit much like light could. So, the waves produced by an electron confined in its orbit about the nucleus sets up a standing wave of specific wavelength, energy and frequency (i.e., Bohr's energy levels) much like a guitar string sets up a standing wave when plucked.

Answer 7

he said that particles like the electron have wave properties.

Answer 9

Yes. The conclusions were supported by experimental evidence and in 1923 Louis de Broglie extended this concept to all particles.
