Let there be light


Tyler Murphy

This a crazy world.

I’m looking around the room and realize I’m not really looking at anything, that’s not exactly how it works. Our eyes are absorbing the reflection of a very limited range of electromagnetic frequencies.

The only thing moving between my mind and my notion of sight, beside a few nerve impulses, are light waves and particles. You see a source of energy (lamp, flash light, the Sun,) cast out visible energy at about 86,000 miles per second. This energy travels in electromagnetic waves but also has the properties of particles, we call it light. (The heart of light: The Photon)

When light strikes an object certain wave lengths are either absorbed or reflected by the surface. When all the spectrums of visible light, from the longest visible wave length, purple, to the shortest, red, are combined they create the luminescence of white light. (Our visible light spectrum)

What we imagine as color are the parts of white light that’ve reflected from an object. Objects that absorb all the colors except for yellow appear yellow, and so on.

So am I seeing the true color of the blue pen in my hand or is it just my limited biology’s best attempt to absorb a narrow bandwidth of whatever energy is reflecting from it? If that’s the case, is there such a thing as color? Or is it just a word to define our limited perception of electromagnetic frequencies? (View how much of entire electromagnetic spectrum were missing out on)

Both I guess?

Just crazy, I tell you… and so wonderfully interesting.
