Intensity Distribution Curve (Pattern)
In Diffraction by single slit intensity distribution curve shows how the brightness changes across the diffraction pattern. It explains how bright different angles or spots on the screen are. The curve usually has a highest point in the middle (which represents the central maximum) and then the brightness decreases gradually towards the secondary maxima and minima. This means that the brightest point in the middle is usually much brighter than the slightly less bright areas around it.
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.

Diffraction is defined as the phenomenon in which light bends around the corners of an obstacle whose size is comparable to the wavelength of the light
