Why a mirror reflects perfectly while a wall scatters light
In short: Understanding specular reflection explains why some surfaces produce clear images while others do not. This video breaks down the physics of how light behaves when it hits different types of materials.
Specular reflection, often called mirror-like reflection, occurs when light reflects off a surface so perfectly that the angle of incidence equals the angle of reflection. This consistency allows for the formation of clear images.
In contrast, irregular surfaces cause diffuse reflection. When a surface is not smooth enough to maintain these precise angles, the light scatters in multiple directions, preventing a distinct image from forming.
