- 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
