- 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
- Predict the direction of rarefaction
- Spectral colours have different refractive indicies
- Different angle of refraction
- TIR
- Prismatic binoculars, endoscopy
- When wave speed increases, the wave bends away from the normal
- Spectral colours have different refractive indicies
- Different angle of refraction
