Light - Coggle Diagram

- - - - We use ray diagrams to show shadows
- - - - The image is laterally inverted
      - Light doesn't come from there so it is a virtual image
  - - - These mirrors produce a virtual image which is upright 1
    - - These mirrors give a go wide view (shops, intersections and cars)
        
        Produces a different image depending on object distance.
- - - - R + G = Yellow
      - G + B = Cyan
      - R + b = magenta
      - All added together = white
      - No coloured light = Black
  - - - Then for example if light goes through a cyan filter then hits a yellow object what will happen is that red will first be Eliminated then blue we be absorbed then green is reflected.
- - - - Light is focused onto the retina by the lens (concave)
      - Retina sends signals to the optic nerve
      - Pupil lets light in
      - the optic nerve sends signals to your brain which allows you to see things
      - Iris controls the size of the pupil to control the amount of light
      - a layer around your eye is the sclera
      - Cornea is a see through layer at the front of the eye
      - The jelly inside your eye Is virtuoso humour
  - - - Fixed with a concave lens
    - - Fixed with a convex lens
- - - - Used a magnifying glasses (the lens in the eye) also in projectors and used to correct long sightedness
    - - Concave lenses are used to give wide view through a "peep hole" to correct short sight
