Wave Theory of Light: A fundamental concept in physics positing that light propagates as transverse electromagnetic waves, explaining phenomena like interference and polarization.
Fresnel Lens: An innovative optical device composed of concentric prismatic rings, designed to focus light efficiently, widely adopted in lighthouses and other optical systems.
Optical Interference: The phenomenon where two or more light waves combine, resulting in a new wave whose amplitude is either increased or decreased.
Optical Diffraction: The bending of light waves as they pass around the edge of an obstacle or through a narrow aperture, causing them to spread out.
