The Frequency of Color

I like science and don't spend nearly enough time thinking about it. It surprises me that so much of it is metaphysical in the popular sense of the word. Here are a few very basic facts on the frequency of color:

1. Frequency refers to the number of times light passes a given point which can be thought of as vibration. Colors with long wavelengths have a low frequency. Colors with short wavelengths have a higher frequency.
2. Red has the longest wavelength and lowest frequency of any color in the visible human spectrum. It has a low vibration or frequency and less energy than other light. Red represents earth and courage and the life-force. It is associated with the root chakra.
3. Redder than red refers to a red whose wavelength is too long for us to see. Infrared light exists beyond the color we perceive as red.
4. Violet has the shortest wavelength which translates into a very high frequency. This color contains the shortest waves we can see. It also contains the most energy. Ultra-violet is a very high vibration violet not visible to the naked eye.
5. Color exists which has a higher frequency than violet. It is invisible to humans and known as bluer than blue. It interests me that blue corresponds to wisdom, spirituality and communication. Blue is significant to me personally, as is red so that made the outside the human spectrum stuff interesting to me. For more on my personal dream experience with color symbolism please see the following entry: The Spirit Dream
6. There are many other wavelengths in the electromagnetic spectrum that which aren't visible to humans. The chart above illustrates this fact as well as all others mentioned.
