  2. Contents • Objectives • History of funhouse mirrors • Law of mirrors • Distorted images • Types of mirrors • Concave mirrors • Convex mirrors • Sources

  3. Objectives • Investigate the types of mirrors used in fun-houses. • Explain how funhouse mirrors give distorted images.

  4. History of funhouse mirrors • Brought out to people by Peter Stuyvesant. • Inspired by the Palace of Versailles. • Peter Stuyvesant built a house of mirrors in New Amsterdam in 1651.

  5. Law of mirrors The main law for mirrors is that the angle of incidence is equals to the angle of reflection. This picture will make the rule clear.

  6. Law of mirrors Even though mirrors are curved, the same rule still applies. While light goes off in all directions from all parts of your body, the only beams that you see in the mirror are the ones that hit your eyes. Beams that are easiest to figure out are beams that are normal to the mirror and beams that come from your eyes, bounce off the mirror, and go right back. Thus, you have to look up to get a perpendicular line for a concave mirror: your eyes appear above you) while convex make you short (you have to look down)

  7. Law of mirrors Boy looks like he has longs legs Why? Girl looks short and fat.

  8. Distorted images Regular Distorted

  9. Distorted images The primary reason for the image to be distorted in the mirror is the shape. The more distorted the shape of the mirror is, the less authentic the reflection is. Regular mirrors are created to be as flat as possible. When there is a flaw or blemish in a mirror, it can be recognised immediately.

  10. Distorted images The angle of the funhouse mirror determines exactly what kind of distortion is created. When the mirror bulges outwards, it makes the image look short and fat(convex). When the mirror bulges inwards, the image looks tall and thin(concave).

  11. Distorted images • Perception is the real secret. When one looks at himself in a funhouse mirror, the brain will assume that rays of light have arrived directly and have not been reflected. In the regular mirror, the image seems to be normal. This is because the brain made the same assumption with a funhouse mirror, but the angle of light has been distorted and so the brain sees the image as fatter, taller, longer, wider etc.

  12. Types of mirrors • Concave mirrors :Are mirrors that bulges inward and away from the light source • Convex mirrors : Are mirrors that bulges outwards and towards the light source.

  13. Types of mirrors Concave mirror- image looks big and broad.

  14. Types of mirrors Concave mirror- Shorter and fatter images

  15. Concave mirrors • A converging mirror. • Bulges inward • Away from incident light. • Reflects light inward to focal point.

  16. Concave mirrors • Mirror shows different images types depending on the distance between the object and mirror. • Mirror image exists in the same space as the real object.

  17. Convex mirrors • Diverging mirror • Bulges towards the light source • Not used to focus light. • Forms a virtual image • Cannot be projected on a screen.

  18. Convex mirrors • Image of object is larger when it is closer to the mirroruntil reaching approximately the size of the object. • Image of object is smaller when it further from the mirror until it is reduced to a point in the focus when the object is at an infinite distance.
