Presentation Transcript

  1. Refraction of light through a Convex Lens

  2. Lens diagram a cross section through the centre plane.

  3. Simple convex (curves outwards) lens

  4. Simple concave (curves inwards) lens

  5. Convex lens Concave lens

  6. Lens is in a vertical plane, straight up and down on the page.

  7. Air Lens Air

  8. Light ray

  9. Light ray is horizontal (at a right angle) to vertical lens

  10. Light ray is horizontal (at a right angle) to vertical lens

  11. Light ray is horizontal (at a right angle) to vertical lens Extension of right ray
