  • Refraction of Waves
    • When wave speed increases, the wave bends away from the normal
      • Decreases- towards the normal
    • Refraction
      • Unusual optical effects e.g. mirages
      • More slowly light travels, higher its refractive index
        • Water=1.3
    • Refractive index= speed of light in vacuum/spee-d of light in medium
      • Predict the direction of rarefaction
        • Degree of bending at  phase boundary refractive
    • Spectral colours have different refractive indicies
      • Different angle of refraction
    • TIR
      • Prismatic binoculars, endoscopy
  • Spectral colours have different refractive indicies
    • Different angle of refraction
