You can put a piece of paper there Virtual image : The rays diverge. But if we look into the rays it appears as if they would come from a certain point: the virtual image point Real Object : Rays start at a real point in space and propagate straight until they hit the optical system Virtual object : Rays appear as if they would have come from a certain point.
