Final answer:
Experimental evidence for the wave nature of electrons includes the double-slit experiment and electron diffraction in crystals.
Step-by-step explanation:
The wave nature of electrons has been experimentally demonstrated through various experiments. One experiment is the double-slit experiment, where a beam of electrons is passed through two slits and an interference pattern is observed on a detector. This interference pattern is a characteristic of wave behavior and shows that electrons can behave as waves.
Another experimental evidence is the diffraction of electrons in crystals. Scientists have observed that when electrons pass through regularly spaced atomic layers in a crystal, they exhibit an interference pattern similar to the interference patterns observed for light passing through slits. This further supports the wave nature of electrons.
Overall, these experimental findings demonstrate that electrons can exhibit wave-like behavior, confirming the wave nature of electrons.
