Position of Secondary Maxima
Secondary maxima are smaller and less intense bright areas close to the brightest spot in a single slit diffraction pattern. They appear because some diffracted waves change direction around the edges of the slit, creating slightly brighter regions away from the brightest spot. This happens because these waves add up and reinforce each other at specific angles, making these areas a bit brighter than their surroundings.
Single Slit Diffraction
Single Slit Diffraction is a fundamental concept in wave optics that explains how light behaves as a wave when passing through a narrow slit. When coherent light (like a laser) goes through a single narrow slit, the waves spread out, and their interaction creates a pattern on a screen placed some distance away. This phenomenon, known as diffraction, leads to the formation of alternating bright and dark regions, showcasing the wave nature of light.
In this article, we’ll learn core concepts, types, and practical applications of Single Slit Diffraction, aiming to simplify and explore its patterns and formulas.
