8-sci 4-3 RC - Coggle Diagram

- - - - depends on distance from object
- - - - cornea and lens
        
        after being reflected, light forms an image in the back of the eye
        
        cells convert into electrical signals
        
        also known as the retina
        
        retina sends electrical signals to the brain.
        
        rod cells see black/white
        
        3 types of cone cells

        cone cells see colors
        
        vision problems can be corrected by changing shape of cornea
  - - - change shape to let in more light
    - - changes shape to adjust focus
    - - objects reflect light with different wavelengths
        
        banannas reflect light with yellow wavelengths
        
        changing the color of light changes how the objects in the light look
      - different objects reflect light and then the retina sends the signals from the reflected light to the brain
      - colors of light emitted by objects
        
        dependent on the wavelength of light emitted
      - white light is the combination of all light colors
        
        a prism allows people to split the light into its colors
