Lights (recompleted)

  1. 1. Lights are a form ofenergy.
  2. 2.  Light rays travels in straight line. The light rays travel away from the light source. White light rays goes trough the prism and got seperated causing different colors of light to come out.
  3. 3.  Luminous objects are objects that can give out light by itself Example: sun, fire, star Moon is not a light source
  4. 4.  Light goes trough the periscope and got reflected to your eyes by mirrors placed in a fixed angle allowing you to see the object on higher or lower ground
  5. 5.  Shadow are created when light rays are blocked by an item. Usually opaque items. Translucent items also created shadow but less darker then the one made by opaque stuff. The closer an object is to the light source the bigger the shadow
  6. 6.  The moon reflects the sun light, like a cat eye reflecting the cars light at night. If a light wave of a given frequency strikes a material with electrons having the same vibration frequencies, then those electrons will absorb the energy of the light wave and transform it into vibration motion.
  7. 7.  A rainbow, forms when the Sun shines on droplets of water. It usually takes the form of a single arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
  8. 8.  Smooth surface is nice to touch. Rough surface is not nice to touch. TeeHee!!!
  9. 9.  a smooth surface would let all the light through in one direction or angle, but a rough surface would make the different rays of light come out at different angles making the different colors more easily visible.
