  1. LOCATING IMAGES INCOVERGING LENSESUSING RAY DIAGRAMS Grade 10 Science – Optics Unit Cardinal Ambrozic C.S.S.

  2. RAY DIAGRAM #1: Object beyond 2F 1. - Incident Ray 1 travels parallel to PA and strikes the lens - Ray is refracted through F 2. - Incident Ray 2 passes through F and strikes the lens 1 - Ray is refracted so it is parallel to PA 3. - Incident ray passes through O (optional) 3 2 O 2F F F 2F 6. Draw the image where the refracted rays meet!

  3. RAY DIAGRAM #2: Object at 2F O 2F F F 2F

  4. RAY DIAGRAM #:3 Object between F and 2F O 2F F F 2F

  5. RAY DIAGRAM #4: Object at F Can we draw a second incident ray through the focal point? O 2F F F 2F Will our two rays form to meet an image? No, therefore NO IMAGE!

  6. RAY DIAGRAM #5: Object between F and the lens O 2F F F 2F
