- 1. Physical optics is a branch of optics that deals with the behavior of light as a wave. It encompasses the study of phenomena such as diffraction, interference, polarization, and other wave-related effects that occur when light interacts with matter. Physical optics is crucial in explaining various optical phenomena, including the formation of rainbows, the colors seen in soap bubbles, and the behavior of light waves in diffraction gratings. By understanding physical optics, scientists and engineers are able to design optical devices and systems that manipulate light effectively for various applications, such as imaging, communication, and sensing.
