Light behavior refers to how light interacts with different materials and environments. It can be described through various phenomena, including reflection, refraction, and diffraction. When light hits a surface, it can bounce back, which is known as reflection. If light passes through a medium, like water or glass, it bends, a process called refraction. Another important aspect of light behavior is diffraction, which occurs when light waves encounter an obstacle or opening. This bending of light waves can create patterns and is essential in understanding how light behaves in different situations, such as in optical instruments like cameras and microscopes.
