  • Optics
    • Convex lenses
      • Refracting telescope
      • Focusing parallel rays of light to a focal point
    • Fat lens-short focal length
      • Thin lens-long focal length
      • The fatter the lens, the more the focus is bent
    • Magnifying lens
      • Virtual image/cannot be reflected- erect (the right way up)
      • Uses: camera, projector, glasses
      • Image size/object size
    • A divergent beam converges light, but not to a focal point
    • Convex lenses can bend light rays so they become parallel
