The colors of light are arranged in order of frequency (or inversely, wavelength) from lowest to highest as: red, orange, yellow, green, blue, indigo, and violet.
Here's a breakdown of how these colors relate to each other within the electromagnetic spectrum:
-
The Electromagnetic Spectrum: Visible light is a small part of the electromagnetic spectrum, which includes radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays. All these forms of radiation are arranged by their frequency and wavelength.
-
Frequency and Wavelength: Frequency and wavelength are inversely proportional. This means that as frequency increases, wavelength decreases, and vice versa.
-
Visible Light: Within the visible light spectrum, each color has a specific frequency and wavelength.
-
Order by Frequency (lowest to highest):
- Red: Lowest frequency, longest wavelength.
- Orange
- Yellow
- Green
- Blue
- Indigo
- Violet: Highest frequency, shortest wavelength.
-
Mnemonic Device: A common mnemonic for remembering the order is ROY G. BIV, where each letter represents a color.
In summary, the colors of light are arranged according to their frequencies and wavelengths, with red having the lowest frequency and violet having the highest.
