Real image/imaginary image

  1. Jun 18, 2005 #1
    hi, i have an OPTICS question .

    i am confused about the "real image" and "imaginary image". could not understand the difference. why a image will be "imaginary image" . images are images. why they have to be imaginary ?

    A real image is like when you look at your computer, and see the computer. It is actually there. A virtual or imaginary image is like when you stand two feet in front of the mirror on the wall. You see the 'image' of yourself about 4 feet away, but in reality the object (you) is not there.

    In ray diagrams , if you draw the rays being reflected/refracted actually meeting, the image is real and if the lines are to be extended to meet , the image is virtual.
