### energy | radiation | light:

Visible light
* Most visible light consists of electromagnetic waves
* Most visible light includes electromagnetic waves
  - turns to heat
* Some visible light is produced by lamps
  - released by lamps
  - penetrates the clouds and heats up the surface ground
* can do so in the presence of an appropriate catalyst.
* cause some damage, but most is caused by ultraviolet light.
* comes from gases heated to only a few thousand degrees like the surface of a star.
* comprises only a tiny portion of the entire electromagnetic spectrum of radiation.
* contains the energy required for biochemical reactions.
* curing adhesives also cure through many translucent UV absorbing substrates
  - also permits bonding of UV blocking and heavily tinted plastics
* divides the electromagnetic spectrum into general regions.
* enters the eye by passing through the clear cornea.
* falls in the middle of the spectrum
  - within a very narrow range in between
* form of electromagnetic radiation that can be perceived by our eyes.
* forms a tiny slice of the electromagnetic spectrum.
* has a limited range of wavelengths
  - wavelength that is just right for the human eye to detect
* is absorbed by chlorophyll, carotenoids, xanthophylls, and flavonoids
  - also electromagnetic radiation and can be used to transmit a signal
  - an example of electromagnetic waves
* is but a small part of the entire spectrum of light waves
  - section of the large spectrum of electromagnetic vibrations
* is composed of all the colors of the rainbow
  - many colors of light, each with distinct wavelengths
  - electromagnet radiation of different frequencies
  - emitted when the excited dye molecule returns to the ground state
* is focused on a specimen with a condenser lens
* is just a small part of the whole spectrum
  - piece of the electromagnetic spectrum
  - section of the electromagnetic spectrum
  - one particular type of electromagnetic radiation
  - light that can be perceived by the human eye
* is made up of all the colors of the spectrum
  - certain wavelengths of radiation
  - many different frequencies of light
  - waves, and can be sorted by wavelength into the colors of the spectrum
  - measured in lumens
  - mostly from sunlike stars
* is one form of electromagnetic radiation, which form of energy
  - small part of the electromagnetic spectrum
  - only a narrow band in the electromagnetic spectrum
* is only a small part of the electromagnetic spectrum
  - the spectrum of electromagnetic radiation
  - portion of the complete Electromagnetic Spectrum
  - segment of the eletromagnetic spectrum
* is only one type of electromagnetic wave
  - way to look at the universe
* is part of the electromagnetic spectrum
  - spectrum, as are x-rays, radio waves, and many other phenomena
  - produced when the photon production increases
  - safe and necessary for life
  - scattered in two different ways as it passes through the atmosphere
  - small part of spectrum
* is the name given to wavelengths to which our eyes are sensitive
  - wavelength of light that is detected by the human eye
  - transmitted with high efficiency
* makes up a fraction of all electromagnetic energy.
* makes up a very small part of the full electromagnetic spectrum
  - just a small part of the full electromagnetic spectrum
  - only a tiny portion of all of the electromagnetic spectrum
* narrow range of wavelengths in the electromagnetic spectrum.
* occupies a sliver between the infrared and ultraviolet
* passes into the greenhouse and is absorbed by material inside
  - through water
* penetrates only a few mm through tissues.
* represents but a fragment of the larger spectrum of electromagnetic radiations.
* runs through blue to green to yellow to orange to red.
* small part of a spectrum of different frequencies of energy
  - portion of the electromagnetic spectrum
* spectrum of colors, which is clear to anyone who has looked at a rainbow.

  * The role of Gamma Proteobacteria in producing light is discussed in detail in reference works. A field guide to bacteria'. Visible light is produced when the photon production increases. In the case of bacteria, the original function of the reaction was probably to detoxify excessive oxygen.
