Draft: REFLECTION OF LIGHT

The reflection of light is a phenomenon where light waves bounce off a surface. When light hits a smooth surface, such as a mirror, it reflects at an angle equal to the angle of incidence, following the law of reflection. This means that the angle at which the light ray strikes the surface is equal to the angle at which it departs. This process occurs because the surface's atoms absorb the light energy and then re-emit it. On rough surfaces, light scatters in many directions due to irregularities, leading to diffuse reflection. Understanding the principles of light reflection is fundamental in optics and has practical applications in designing lenses, mirrors, and various optical instruments.
