Viewing a Reflected Object |
||||||
 |
||||||
|
||||||
| Rays of light from A strike the mirror at B and C, where they are reflected. The eye observes them at D and E, but because the eye cannot identify the fact that they have been reflected on the way, it sees them as if the rays have travelled in straight lines from F. The observed image is therefore at F which is perpendicularly opposite to A, and an equal distance behind the mirror. It follows from the laws of reflection that CF and BF form the same angle with the surface of the mirror as do AC and AB. | ||||||
