FAQ About Christiaan Huygens

The wave theory of light, proposed by Christiaan Huygens in 1678, suggests that light behaves as a wave rather than as particles. Huygens postulated that each point of a wavefront can be considered as a source of secondary spherical waves, a principle now known as Huygens' Principle. This theory accounted for various optical phenomena, including reflection, refraction, and diffraction.
