[Physics] Why can’t we see real images

geometric-opticsoptics

When light from an object passes through a convex lense, it gets reconverged at a single real image. From there, the light rays presumabely begin diverging again, exactly as if there was a light-emitting object sitting at the real image point.

Why is it that if we look at the real image point, we don't see a hologram of the object sitting there?

You're operating under a misconception. When a real image is formed, we can see it, provided that our eye is positioned in a location such that rays from the image can enter your eye. Compared to a hologram, the situation is different for a couple of reasons. (1) The possible locations of your eye are more restricted. (2) You may pick up psychological cues such as the framing of the field of view, which cause your brain not to interpret the real image as being where it actually is.

By the way, the word is spelled "lens," not "lense," and it is not always true that a convex lens produces a real image.
