8. Production of large size wall mirrors The second half of 17 th C -Baroque Period The Versailles -Hall of Mirrors -Louis XIV Introduction of Silver Nitrate

9. How mirrors are made… Float Glass -a much greater quality! ->very important to make good mirrors Wash by deionised water & cerium oxide Spray a thin layer of tin -promote the adhesion of the silver Silvering, Coppering, Coating…

10. Red ox Reaction R -> Reducing agent Ox -> Oxidizing agent M n+ -> Ionized metal

11. How mirrors work.. Smooth surface of silver -Doesn’t absorb the light or -doesn’t scatter the light ->Reflect the light perfectly

12. Human eyes.. “Everything that can be seen is seen only when light from that object travels to our eyes.” Object distance = Image distance law of reflection

13. Human eyes… In order to see the image of an object in a mirror, you must sight at the image; when you sight at the image, light will come to your eye along that line of sight.

14. Human eyes… the orientation of the image ->left-right reversal

15. Use of the Mirror To observe figures To make space look wider.. To make rooms brighter…
