Newtonian optics

Newtonian optics is the study of light's behavior using theories developed by Sir Isaac Newton. It focuses on how light travels in straight lines, reflects off surfaces, and refracts when passing through different materials, like lenses. Newton introduced the idea that white light is made up of a spectrum of colors, which can be separated by prisms. This branch of optics lays the groundwork for understanding vision, photography, and various optical devices. It emphasizes the particle nature of light, contributing to our broader understanding of electromagnetic wave behavior in physics.
