light interference patterns

Light interference patterns occur when two or more light waves overlap and combine. This can create areas of brightness, where waves reinforce each other, and areas of darkness, where they cancel each other out. A classic example is the colorful patterns seen when light passes through a thin film, like soap bubbles. The varying thickness of the film causes different wavelengths of light to interfere in unique ways, producing a spectrum of colors. These patterns illustrate fundamental properties of light, demonstrating both its wave nature and the principle of superposition, where multiple waves coexist and interact.
