slit apparatus

A slit apparatus is a device used in physics experiments to study light and diffraction. It features a narrow slit through which a beam of light passes. When light goes through this slit, it spreads out and creates patterns of bright and dark areas called diffraction patterns. These patterns help scientists understand the wave-like behavior of light, measure wavelengths, and analyze wave properties. The apparatus typically includes a light source, the slit, and a screen to observe the resulting pattern, making it a fundamental tool for exploring the wave nature of light and interference phenomena.
