Light and Color:

---

Color and Frequency: Frequency and wavelength are very similar. When the wavelength or the frequency is within a visible spectrum it is then noticeable by the human eye. There range is within various colors. When the speed of light through a vacuum is multiplied by wavelength you get the frequency.

Explain:

color	wavelength interval	frequency interval
red	~ 700–630 nm	~ 430–480 THz
orange	~ 630–590 nm	~ 480–510 THz
yellow	~ 590–560 nm	~ 510–540 THz
green	~ 560–490 nm	~ 540–610 THz
blue	~ 490–450 nm	~ 610–670 THz
violet	~ 450–400 nm	~ 670–750 THz

The wavelength interval and the frequency interval are very much similar, but wavelength uses nm, and frequency uses THz.

Color and wavelength: Wavelength is another way to say light waves. The equation for wavelength is the speed of light in a vacuum/ divided by its frequency. The primary colors are Red, Blue, and Green. White is a combination of all the colors. Black light is absent of color. A wavelength has a peak and a trough, as it travels.

Explain:

Our visible light is very small compared to all the rays on the spectrum.Where Red, Blue, and green are the primary colors. But colors like yellow, orange, purple, neon, peach, those are all composite colors that are created when the primary colors merge together.

Energy of light: (equations):

E=MC^2 Energy equals the mass times the velocity of energy squared
