- The color of light we observe is determined by the Wavelength or Frequency of light that passes through our eyes and interpreted by our brain.
- The only perceived wavelength of colors in the electromagnetic spectrum is the Visible Region, with red having the longest wavelength and violet having the shortest.
- Emission spectroscopy measures the wavelength of light emitted by electrons when they drop from a higher energy level to a lower energy level, while absorption spectroscopy measures the wavelength of light absorbed by a cooler material when a hot object passes through it.
