The Science of Light, the Heartbeat of the Universe
A particle, a wave, an energy field, the speed police … what is light?
“The vastness of the heavens stretches my imagination — stuck on this carousel my little eye can catch one — million — year — old light. A vast pattern — of which I am a part… What is the pattern, or the meaning, or the why? “ — Richard Feynman
Light. One of nature's wonders, that we take for granted because we see it every day. Literally, we not only see it — but we see nothing but it.
Seeing is defined as interacting with the electromagnetic waves, from the radiation from the sun rays, the photons hitting our detector eyes, there are many words for the same. Rays are scattered, different wavelengths give us different colors, everything we see is light by definition.
If we define light broadly as every radiation on the electromagnetic spectrum, then there is more to light that we catch our vision. Our eyes are a set of detectors, that can detect electromagnetic waves, but only in a specific range of wavelengths.
