Definition and Importance
Wave optics, also known as physical optics, is the branch of optics that deals with studies of light as a wave phenomenon. It is essential for understanding various optical phenomena that cannot be explained by geometric optics alone, such as interference, diffraction, and polarization.

Historical Background
The wave nature of light was first proposed by Christiaan Huygens in the 17th century. Thomas Young’s double-slit experiment in the 19th century provided strong evidence for the wave theory of light, which was further developed by scientists like Augustin-Jean Fresnel and James Clerk Maxwell.
Applications in Technology
Wave optics principles are applied in various technologies, including:
