Objectives: *that when light is reflected from plane surfaces an image is formed
The cat might think he's a lion, he maybe the king of his own jungle in the back garden, but it is not a true reflection. When we look in a mirror we expect to see a true reflection of ourselves. A mirror can be defined as a surface capable of reflecting sufficient undiffused light to form a virtual image of any object placed in front of it. There are many forms of mirrors, in this unit we are considering flat or plane mirrors and the effects achieved when light is reflected from them.
Mirrors do not have to be man made. Any surface that is smooth and shiny can and do act as mirror.
In order to see the image of an object in a mirror, you must look at the image; when you look at the image, light will come to your eye along that line of sight.
Image of How we see images in a mirrorWhen we place two or more mirrors together we can great some splendid and interesting effects. A kaleidoscope uses three mirrors to create its spelndid effects. These mirrors can be rotated, giving ever changing patterns.
