WebDiverging Lens Image Formation. Diverging lenses create virtual images since the refracted rays do not actually converge to a point. In the case of a diverging lens, the image location is located on the object's side of the lens where the refracted rays would intersect if extended backwards. Every observer would be sighting along a line in the ...

Use the thin lens equation: Since f < 0 and d o > 0 by convention, ( positive) + 1 d i = ( negative) implies that d i < 0, making the image a virtual one. By combining a divergent lens with a convergent one, however, a real image can be ... WebFeb 27, 2024 · Since the rays started out from the same point on the object, the point where the traced lines intersect will be the place where the image will be formed.
