### energy | radiation | light:

Blue light
* Most blue light comes from bulbs
  - has energy
  - is absorbed by chlorophyll
  - provides energy
* Some blue light promotes growth
  - vegetative growth
* activates a specific protein kinase in higher plants.
* are to be used when a person needs immediate assistance from security.
* causes the photoconductor to conduct.
* dominates and the stars are blue.
* enhances protein synthesis
  - the excretion of bilirubin through photodegradation
* has a a. shorter wavelength and a higher energy than red light
  - higher frequency than red light
  - longer wavelength than green light
  - much, much shorter wavelength than red light
  - short wavelength and scatters more thank red light
* has a shorter wavelength and is more energetic than red light
* has a shorter wavelength than red light, which has a number of technological advantages
  - the rest of visible light
  - capability
* has more energy than most other colors
  - penetration capability
  - the shortest wavelength and red light has the longest
* induces phosphorylation at multiple sites on a pea plasma membrane protein.
  - bent most and therefore focuses closer to the lens than red light
  - emitted by oxygen atoms, red light by sulfur atoms, and green light by hydrogen atoms
  - higher energy than orange light
  - light waves
  - much more likely to scatter than either yellow or red light
  - on the short wavelength end of the visible electromagnetic spectrum
  - primarily responsible for vegetative growth or leaf growth
* is scattered more than red, making light scattered from the sky blue
  - most and red light is scattered least
* is scattered much more than orange or red light
* is the dominant component of skylight and a major cause of glare
  - light that irritates the eye
  - transition from the visible to the ultraviolet spectrum
  - transmitted through while the red and green light are absorbed
  - useful to show blood trails as dark black
* mediates positive phototropism while far-UV light mediates negative phototropism.
* provides energy for photosynthesis
  - sufficient energy
* regulates many aspects of plant development.
* scatters more readily than does red light.
* sustains development.
* travels farther than red light.

Bolide
* are fireballs that explode at the end of their paths
  - larger pieces that explode, and leave behind a magnificent glowing trail
  - meteors
* is light
* produce their brilliant light shows miles above Earth's surface
  - tens of miles above Earth's surface

### energy | radiation | light:

Bright light
* Most bright light produces leaves.
* Some bright light affects behaviour
  - reduces visibility
* acts as a reset button, triggering the molecular activity to start earlier or later.
* are on day and night.
* attract big bugs.
* attracts nocturnal insects.
* can also become a safety problem, endangering motorists blinded by glare
  - be effective in repelling bats
  - bounce off surfaces
  - discourage drowsiness, and darkness can cause sleepiness, day or night
  - overstimulate photoreceptors and potentially damage the retina
* causes many children to become hyperactive.
* consume a lot of battery power.
* increases the secretion of melatonin in the brain.
* intensifies the leaf colorations and promotes good flower development.
* is capable of blinds
  - essential for rich color development in the leaves
* is essential to keep geraniums flowering
  - in flower year-round
  - located in hospitals
* put astronomers in the dark.
* reflects dark shadows.
* represent the urban-metropolitan areas.
* seems to inhibit the feeding process.
* signals the body to be active while darkness signals that it is time for rest
  - brain that it's time to wake up
* suppress the brain's secretion of melatonin.
* suppresses the output of melatonin.
* tends to increase alertness while dim light leads to drowsiness.
