The Merging of the Particle and Wave Concepts: Evidence Suggesting that the Sub-atomic Particle is a Quantized Excitation Wave

In the 1920s, it was discovered that a massive particleParticle can behave like a waveWave. This discovery was mainly due to a bold hypothesis put forward by de BroglieDe Broglie. He proposed that not only light wavesWave can have particleParticle properties; particlesParticle with mass (such as electronsElectron) might also have waveWave properties. His hypothesis was soon confirmed in experiments. Davisson and Germer reported that the electronElectron diffraction results were similar to that obtained by diffraction using X-rays. The double-slit experimentDouble-slit experiment also demonstrated that the electronElectron behaves like a waveWave. Another strong reason to believe that the electronElectron is a physical waveWave is the fact that an electronElectron can be created or annihilated in the vacuumVacuum. It is very difficult to explain these observations if one regards the electronElectron as a point mass.
