The double-slit diffraction pattern, a cornerstone of quantum physics, arises when a coherent light source passes through two closely spaced slits, creating interference fringes on a screen. These fringes result from the superposition principle, where light acts as both a wave and a particle, traveling through both slits simultaneously. The spacing between the fringes is inversely proportional to the wavelength of light, providing a tool for determining the wave nature of light. Moreover, the pattern changes depending on whether the particles passing through the slits are electrons, photons, or other quantum particles, showcasing the wave-particle duality that is a defining characteristic of quantum mechanics.
Define diffraction and interference.
