This vidclip shows how to construct a ray diagram that illustrates that the virtual image formed in a plane mirror is erect, the same size as the image and laterally inverted - you need to view video 1 in this series in order to construct the image quickly - it tells you how to cheat!

  • in concave, plane and convex mirror the ray of light do not pass through the mirror it refletc then how image is formed in the mirror.

  • @TheDevilvivek Images are either real or virtual.... virtual ones are formed by our brains when diverging rays enter our eyes. The brain calculates that they come from a point and tell us that the point of the image is there.

  • :)

  • what is the angle of the two rays from the object point? is it anything or a fixed angle?

  • @NOCOMMENT3176 The angle could be anything. In reality there are millions of 'light rays' coming from the object - the diagram just shows the path of two of them. Just choose two which illustrate what happens - the examiner often gives you the rays you need to continue to find an image point.

  • @TheDevilvivek You seem very confused - I suggest you talk this out with a physics teacher who has the equipment to show you practically what is going on.. These diagrams do not show how a full image is formed they show how the image of ONE POINT on the object is formed. See info on images in a mirror - lateral inversion.

  • @TheDevilvivek If you look at the diagram on the webpage I directed to you that is what the diagram shows. I cannot help you as I cannot see your problem. The page shows diagrams for all of the positions.Look at the webpage: cyberphysics.co.uk/topics/ligh­t/concave_mirror_construct.htm
