Study Notes
Lenses
- Light bending through a material is called refraction.
- The point where light rays meet is the focal point.
- A convex lens is thicker in the middle.
- A concave lens is thinner in the middle.
- Light slows down when passing from air to glass.
- Concave lenses diverge light (spread it apart).
- Convex lenses converge light (bring it together).
Lens Types
- Convex lens characteristics:
- Thicker in the middle
- Curved outward on both sides
- Focuses light
- Concave lens characteristics:
- Thinner in the middle
- Curved inward on both sides
- Diverges light
Image Formation by a Converging Lens
- Object's distance from the lens is greater than 2F: Image is inverted and reduced.
