How Light Actually Works _ The Sleepy Scientist
"Light is not a simple ray. It is a wave, a particle, and the reason you can see this text, all at the same time."Light travels at 299,792 km/s, the cosmic speed limit [citation:4]. It behaves as an electromagnetic wave when it bends and spreads, and as a stream of photons when it interacts with matter [citation:1][citation:5]. A red apple is not red in the dark—it reflects the red wavelengths of the light that hits it [citation:1][citation:3]. Newton proved white light is a mixture of all colors with a prism [citation:1]. This is the quiet science of the universe's oldest messenger.
