### energy | radiation | light:

Yellow light
* are far less attractive to night-flying insects.
* can also heal muscle cramps, hypoglycemia and gall stones.
* is absorbed in great concentrations by the red pigment found in blood
  - in the middle of a rainbow
  - next up the spectrum from orange
  - traffic light
  - yellow
* longer wave length and less energetic form of visible light.
* stops flashing when batteries are low.

Zodiacal light
* function of the relative position of the sun and the telescope pointing.
* is reflection

Microwave radiation
* can also do a lot of damage to humans
  - produce heat too
* form of radiation that is related to visible light, X-rays and gamma rays.
* has considerable potential in sorption and decomposition of VOCs.
* is absorbed and emitted by the Earth's surface and atmosphere
  - another region in the spectrum
  - emitted by the Earth's surface and by water droplets within clouds

Much ultraviolet radiation
* causes cancer
  - skin cancer
* penetrates skin.

Natural radiation
* alters structures.
* occurs in rock and soil.

Net radiation
* is determined by inputs and outputs of solar and terrestrial radiation
  - measured as watts per square meter
  - the difference between all incoming and all outgoing radiation
* represents energy available to do work.

### energy | radiation:

Nuclear radiation
* can be both extremely beneficial and extremely dangerous.
* can cause biological damage because it is highly energetic
  - casualties and delay movements
  - skin irritation
  - contaminate food and water
* causes environmental disaster, sickness and death.
* comes in several forms.
* is deadly for hundreds of thousands of years.
* is known to cause cancer, particularly leukemia
  - influence our immune system
  - said to be mutagenic in that it can damage or mutate the genetic code of cells

Particulate radiation
* consists of atomic nuclei or subatomic particles moving at high velocities.
* includes alpha and beta radiation.
* is more threatening to humans
  - radiation in the form of particles
  - radioactivity
* poses the greater threat to humans.

### energy | radiation | radio emission:

Long wave
* Teleswitching Long wave teleswitching new way in load management technology.
* are barotropic
  - radio waves
* can travel far into the ice field and have strong influence on braking up the ice field.
* have a lower frequency than short waves.
* move very slowly.
* radio emission

### energy | radiation | radio emission:

Radio signal
* are a form of electromagnetic waves and travel with the speed of light
  - electromagnetic waves that are sent from a transmitter to one or more receivers
* can start engines moving so that gates open on their own from a distance.
* is subject to electrical interference.
* occupy certain ranges of the electromagnetic frequency spectrum.
* propagate in different ways at different frequencies, locations and times.
* travel through the air at a speed very close to the speed of light.
  * Television also uses radio signals to send pictures and sound. Radio signals can start engines moving so that gates open on their own from a distance. Radio signals can be used to lock and unlock the doors in a car from a distance.

Short wave
* are radio waves.
* can do constructive or destructive interferences with long waves.
* infrared is color sensitive
  - recognized as white light
* penetrate the skin and warms the fat.
* tend to transfer more energy per second than long waves.
