Theories of Optics

Theories of optics describe how light behaves and interacts with objects. The wave theory sees light as waves that can bend (diffraction), spread (dispersion), or interfere. The particle theory treats light as tiny particles called photons, explaining phenomena like reflection and the photoelectric effect. The quantum theory combines these ideas, describing light as both wave and particle, depending on the situation. These theories help us understand everything from how lenses focus light to how colors form. Each offers a different perspective that, together, provide a comprehensive understanding of light's nature and behavior.
