Reflection in optics involves light bouncing off surfaces, shaping phenomena like mirrors. Sir Isaac Newton studied light and color, laying foundation for optics; Thomas Young demonstrated light’s wave nature via interference. Snell's Law describes how light bends when passing between different materials; Fresnel equations quantify reflection and transmission at interfaces. Total internal reflection occurs when light stays within a medium, enabling fiber optics. Lenses and mirrors manipulate light for vision and imaging. Ray optics models light as rays, while wave-particle duality reveals its dual nature. Huygens' and Fermat's principles explain wave behaviors and light’s shortest path. Optical fibers transmit data; all are central to modern physics.
