| Front | refraction |
| Back | bending of waves when they enter a new medium due to a change in speed |

| Front | conditions for TIR |
| Back | only reflection within a denser mediumi > c |

| Front | uses of TIR optical fibres |
| Back |
 optical fibres - light signals passing through greater than critical angle - light is always totally internally reflected - prevents loss of light carrying signals |
