Optical phenomena refer to any observable events that involve the interaction of light with matter. This research area encompasses a wide range of phenomena, including reflection, refraction, diffraction, scattering, interference, polarization, and dispersion. Researchers in this field study how light behaves in different materials and environments, as well as how it can be manipulated for various applications, such as in optics, photonics, imaging, and telecommunications. Optical phenomena are fundamental to our understanding of the physical properties of light and play a crucial role in the development of new technologies.
