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

  15. 15. Light Sources <ul><li>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. </li></ul>
  16. 16. Light pollution <ul><li>There are different types of light pollution:Light trespass, over-illumination, glare, clutter, and sky glow. </li></ul><ul><li>Light trespass occurs when unwanted light enters one's property. </li></ul><ul><li>Over-illumination is the excessive use of light </li></ul><ul><li>Glare is the result of excessive contrast between bright and dark areas in the field of view </li></ul><ul><li>Clutter refers to excessive groupings of lights. And Sky glow refers to the &quot;glow&quot; effect that can be seen over populated areas. </li></ul>
