Wave Optics
Wave optics studies light as a wave, focusing on phenomena that geometrical optics cannot explain, such as interference and diffraction. While geometrical optics treats light as straight rays, wave optics reveals how light waves can overlap, creating patterns of bright and dark spots. This approach is crucial for technologies like lasers and optical instruments. It encompasses electromagnetic waves, describing light's behavior as part of a spectrum, and incorporates concepts from Fourier optics, which analyzes light in terms of its frequency components. Together, these principles provide a deeper understanding of how light interacts with matter and forms images.

Wave optics, also known as physical optics, studies how light behaves as a wave rather than just a particle. This approach helps explain phenomena like interference and diffraction, where light waves overlap and create patterns of bright and dark areas. For example, when light passes through small slits, it spreads out and creates distinct patterns. Wave optics is essential for understanding various technologies, such as lasers and optical instruments, and is crucial in fields like telecommunications and imaging. By recognizing light's wave nature, we gain deeper insights into its interactions with materials and the environment.
