I m really confused between virtual and real images.
While doing a convex lens experiment using optical bench (I have attached an image), when I look through the lens I see an inverted image. As this image is seen when I look through the optical instrument, so it is a virtual image.
Here's a similar ray diagram of my experiment.
According to this ray diagram the image is a real one, and will be seen if a place a screen at that point. So why am I able to seeing a virtual image when I look through the convex lens?
The ray diagram is just a representation and is not up to proper scale. Further the captain "Image needle" is not used to signify the image but to signify the needle which is will be used in the experiment to remove parallax error.
