Learning Outcomes

  • By the end of this worksheet students will be able to:
  • ☑   Explain refraction and describe the refractive index, using water and prisms as examples.
  • ☑   Describe the law of refraction.
  • ☑   Describe convex and concave lenses.
  • ☑   Describe how light refracts through convex and concave lenses.
  • ☑   Define focal point, focal length, principal axis, mid-plane and optical centre.
  • ☑   Describe how lenses in the eye focus light.
  • ☑   Differentiate between near-sightedness and far-sightedness and describe how they can be corrected with lenses.
  • ☑   Draw ray diagrams to determine the images produced by convex and concave lenses.
  • ☑   Differentiate between real and virtual images produced by lenses.
