Louis De Broglie proposed in 1924 that electrons and other particles exhibit wave-like properties described by an equation relating the wavelength of a particle to its momentum. De Broglie's equation showed that all moving particles can be associated with a wavelength, and calculated wavelengths for everyday objects like cars and baseballs, though the wavelengths are too small to detect directly. The wavelength of electrons calculated using the equation could be measured using specialized equipment, providing evidence for the wave-particle duality of matter.

3. If waves can have particle like characteristics, then can particles, such as electrons, have wave like characteristics???
