### energy | radiation | light | meteor:

Larger meteor
* burn up as they enter the earth's atmosphere, creating fleeting streaks of light.
* can sometimes fall to Earth intact where they are called meteorites.

Normal meteor
* are only visible at night.
* leave behind trails that fade in seconds.

Monochromatic light
* has one frequency.
* is described by only one frequency
  - light in which all photons have the same wavelength
  - passed through the capillary at each position using a fiber-optic cable
  - shone on the electrode surface at a succession of wavelengths

Moonlight
* are light waves
  - software
* includes moonbeams
  - photons
  - sections
* is capable of producing wonder
  - little more than sunlight reflected off a moon
  - the enemy of meteor watchers because it can wash out fainter meteors
  - very alkalizing and greatly benefits the thyroid and pituitary glands
* steals color from whatever it touches.

### energy | radiation | light | moonlight:

Bright moonlight
* can illuminate an earthly landscape on nights when the moon is full.
* makes it difficult to see all but the brightest meteors.

### energy | radiation | light:

Natural light
* Some natural light provides warmth.
* affects colors differently than artificial light.
* combination of two polarization states.
* coming from windows is one thing that creates glare.
* dynamic resource that varies diurnally, seasonally, and with orientation.
* energizes the environment for people.
* enters through a clear polycarbonate dome.
* gives the time of day and the mood of the seasons to enter.
* is best for photos, although skilled photographers can use strobes effectively.
* is best, but some plants can also thrive in office fluorescent light
  - however, some plants also can thrive in office fluorescent light
  - comfortable for people to work in
  - maximized with skylights and windows
* is more conducive to learning
  - pleasing than harsh flashes
  - never completely pure
  - primarily ambient, though it can be sufficient for daytime tasks near a window
  - subject to constant variation
  - the strongest influence on a room, then the architecture of the space
* makes most things look better indoors.
* potential remedy for jaundice in newborns.
* reduces the symptoms of depression associated with the dark winter months.

Navigation light
* Some navigation light is part of aeroplanes
  - airplanes
* are essential for boats out after sunset.
* is light

Night light
* can help to light exit paths in an emergency
  - make it easier to walk in the house at night and reduce the risk of falls
* come in a whole variety of shapes and figures.
* is light
  - located in bedrooms
* use less electricity than leaving higher wattage lights on at night.

Ordinary light
* can be a mixture of many wavelengths.
* has many wavelengths that go off in all directions.
* is composed of waves that vibrate in all directions perpendicular to the light beam.
* is made up of a broad range of wavelengths and has relatively low energy
  - range of wavelengths, from ultraviolet to infrared
* mixture of light of many different colors, i.e. wavelengths.

Outdoor light
* act to attract insects to the house.
* comes in many different forms.
* has a different quality to indoor lighting.
* operate on photo cells turning on and off automatically.
