Transcript

  • 1. Light
    Light Refraction
  • 2. Light Refraction
    When light passes from one medium to another, it changes direction
    Bending / changes direction of light is known as light refraction
  • 3. Refraction of Light
  • 4. Refraction of Light
    If the light travels along the normal, it does not bend
  • 5. Refractive Index
    Angles of incidence, i measured between normal and incident ray
  • 6. Refractive Index
    Angles of refraction, r measured between normal and refracted ray
  • 7. Refractive Index
    Angles of incidence, i > angles of refraction, r  refracted towards normal
    Angles of refraction, r > angles of incidence, i  refracted away from normal
