Refraction in a glass block

Cards in this deck (12)

  1. 1Refraction in a glass blockRefraction is change of speed between two substances of different densities.
    Less dense to more dense towards normal
    More dense to less dense away from normal    Refraction in a glass block
  2. 2Wavefront diagramsSpread from centre
    Connect all peaks produced on wave at same time    Wavefront diagrams
  3. 3Wavefront diagram for refractionFrequency stays same but wavelength gets smaller at bottom
    Wave must have slowed down in the more dense substance    Wavefront diagram for refraction
  4. 4Refraction in eyesEnter text here...Refraction in eyes
  5. 5Examples of how waves behave in different substancesSkin absorbs UV radiation but reflects visible light
    Bones absorb X-rays but muscle and skin tissue transmits them
  6. 6Convex lensesFound in telescopes, microscopes, cameras and eyes
    Curved transparent block. Thicker in middle    Convex lenses
  7. 7MagnificationMagnification = image/object
  8. 8Forming an imageAll rays of light from one point of object must be brought together at the same point on the image
    RAYS CONVERGE
  9. 9Concave lensesThe rays diverge
    Image formed by diverging lense is always virtual, upright and diminished    Concave lenses
  10. 10Ray diagram for concave lensesEnter text here...Ray diagram for concave lenses
  11. 11Ray diagram for convex lensesEnter text here...Ray diagram for convex lenses
  12. 12Ray diagram for no imageEnter text here...Ray diagram for no image
