    • The speed of light is estimated to be 227,000 kilometers per second.
    • It takes 3 seconds at the speed of light to get to the sun.

  • 3.
    • There are many sources of light. The most common light sources are thermal: a body at a given temperature emits a characteristic of black body radiation.

  • 4.
    • “Many of the effects of natural light may put whole ecosystems in danger.”
    • By changing the environment on which animals develop and reproduce, natural light effects their lives and the growing of their species.”
    Enviromental effects of light
  • 5.
    • Categories of light pollution include light trespass, over-illumination, glare, clutter, and sky glow.
    • Light trespass occurs when unwanted light enters one's property by shining over a neighbor’s fence.
    • Over-illumination is the excessive use of light.
    • Glare is the result of contrast between bright and dark areas in the field of view.
    • Clutter refers to continues groupings of lights.
    • Sky glow refers to the "glow" effect that can be seen over populated areas.

    • Many of the effects of natural light may put whole ecosystems into imbalance.
    • By modifying the playing field on which animals develop, meet, and reproduce, natural light their lives and the growing of their species.

  • 14. Light Speed
    • Light travels 299,792,458 meters per second.
    • In water, the speed of light slows to 140,000 miles per second. Its speed is 124,000 per second in glass. Through a diamond, the speed of light is 77,500 miles per second.
  • 15. Light Sources
    • There are many sources of light and one of the sources are thermal light: a body of given temperature emits a characteristic of black body radiation.
  • 16. Light pollution
    • There are different types of light pollution:Light trespass, over-illumination, glare, clutter, and sky glow.
    • Light trespass occurs when unwanted light enters one's property.
    • Over-illumination is the excessive use of light
    • Glare is the result of excessive contrast between bright and dark areas in the field of view
    • Clutter refers to excessive groupings of lights. And Sky glow refers to the "glow" effect that can be seen over populated areas.
  • 17. Environmental effects of light
    • “ Many of the effects of natural light may put whole ecosystems in danger.
