Interference fringes

Interference fringes are patterns of bright and dark lines that occur when two or more waves, such as light waves, overlap and combine. When the waves are in sync, they reinforce each other, creating bright fringes; when out of sync, they cancel out, producing dark fringes. This pattern reveals the wave nature of light and is commonly observed in experiments like the double-slit setup or thin film interference. The fringes depend on the wavelength, the distance between sources, and the angle of observation, providing insight into wave behavior and properties.
