Refraction
- Define
- Refraction
- Refractive Index
- Critical Angle
- Total Internal Reflection
- State
- Laws of Refraction of Light
- Snell's Law
- Explain
- Real Depth
- Apparent Depth
- Optical Fibre
- Experiments
- Demonstrate Refraction
- Verify Snell's Law
- Measure Refractive Index
- Demonstrate total internal reflection
- Formulae
- n = Sin i / Sin r
- n = real depth/apparent
depth
- n = 1/Sin C
- List
- Practical effect due to refraction
- Show
- How a prism can be
used to turn a ray of light
through 90 and 180
- Recall that :
- Reflective road signs,
mirages, prism reflectors
and optical fibres are based
on total internal reflection
