Weblight, electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10−11 metre to radio waves measured in metres. Within that broad spectrum the wavelengths visible to humans occupy a very narrow band, from … WebEinstein was the first to explain what was happening. He theorized that electromagnetic energy comes in packets, or quanta which we now call photons. So light behaves as a wave and as a particle, depending on the circumstances and the effect being observed. This concept is now known as wave-particle duality. Einstein won the 1921 Nobel Prize in ...
