  • TIR is when light travels to a material of lower refractive index, all light is reflected at the boundary
  • Conditions for TIR
    1. n1 < n2
    2. θi > θc
  • Travelling to a higher refractive index means light is slower, so ray bends towards normal
  • Travelling to a lower refractive index means light is faster, so ray bends away from normal
