Matter-wave interference

Matter-wave interference occurs when particles like electrons or atoms behave like waves, exhibiting patterns similar to water waves or light waves. When these particles are directed through two slits or around obstacles, their associated waves overlap and combine, creating regions of constructive interference (bright spots) and destructive interference (dark spots). This phenomenon demonstrates the wave-particle duality of matter, showing that particles can exhibit wave-like behavior under certain conditions. Essentially, matter-wave interference reveals that at a quantum level, particles have a wave nature that causes their probabilities to interfere, producing observable patterns that reflect their underlying quantum properties.
