Experimental set-up
  1. Take a chess board.
  2. If a chess board is not available, draw on a chart paper \(64\) (\(8\ ×\ 8\)) squares of equal size.
  3. Draw a thick line in the middle of the paper.
  4. Fix a plane mirror vertically on this line.
  5. Place any object at the boundary of the third square counting from the mirror (Figure).
  6. Note the position of the image.
  7. Now shift the object to the boundary of the fourth square.
  8. Again note the position of the image.
Did you find any relation between the distance of the image from the mirror and that of the object in front of it?
 
, the image formed behind the mirror is at the  as the object in front of the mirror. This can be verified by placing the object anywhere on the board.
