Single Slit and Laser

A laser beam is passed through a single slit, producing a diffraction pattern on a screen. The width of the slit determines the pattern's characteristics, with narrower slits producing wider diffraction patterns. The resulting pattern, with a central bright fringe and alternating dark and bright fringes, illustrates the wave nature of light and the principle of diffraction. The angular width of the central maximum is inversely proportional to the slit width, demonstrating the relationship between slit size and diffraction angle.
