If we can see a virtual image, why cant we obtain it on a screen?
Because with a virtual image the light creating the image does not really originate at the apparent location of the image--and you need light in order to focus an image on a screen.
but then, isnt the retina of the eye a screen?
Sure. That's why the eye must focus a real image on the retina.
ah ok..so if we keep a lens in the place of the eye then we can obtain it on a screen behind the lens right? i'll just try that out..
thanks to my 8th grader younger bro to ask this question to me, so i now know how little physics i know :D
and of course thanks doc.
Yes, do try it. A magnifying glass should work.
