Ray Model of Light - Coggle Diagram

- - - - Reflects light
    - - Gives off light
  - - - An opaque object can reflect light
    - - Light rays travel in straight lines if they travel in the same medium
    - - The more transparent an object is, the less light it will absorb
      - An opaque object can absorb light
- - - - Regular reflection = clear images
    - - Diffused reflection = unclear images
  - - - Concave
        
        Curved inwards (like a cave!!)
        
        Images are...
        
        Magnified
        
        Upright
        
        Virtual
        
        Eg. dental mirrors/car headlights/microscope base
      - Convex
        
        Curved outwards (Convex sounds like flex = bend out)
        
        Images are...
        
        Upright
        
        Diminished
        
        Virtual
        
        Wide field of vision
        
        Eg. Blind corner mirror on the road. Easy to remember what convex mirrors are by this example because we can easily recall what a blind corner mirror looks like (curve out)
    - - Images are...
        
        Upright
        
        Same size as the object
        
        Virtual
        
        Image appears as far behind the mirror as the object is in front of the mirror
        
        Laterally inverted = right becomes left and vice versa
      - Uses
        
        To check appearance
        
        To make spaces seem larger/wider (eg. in house/office)
        
        In optical instruments (eg. periscope)
- - - - Draw with arrows
    - - No arrows
