👉 Last-light particles, often referred to as photons, are fundamental components of light. These particles are incredibly small, with wavelengths that range from about 400 nanometers (violet light) to 700 nanometers (red light), corresponding to frequencies from approximately 430 terahertz to 790 terahertz. Photons are massless and exhibit both wave-like and particle-like properties, a duality central to quantum mechanics. They carry energy and momentum and are the quanta of electromagnetic radiation, meaning they are the discrete packets of energy that make up light. When light interacts with matter, photons can be absorbed, emitted, or scattered, playing crucial roles in phenomena such as photosynthesis, vision, and the transmission of information through fiber optics.
