This question already has an answer here:
I am trying to learn about optics and I am having a hard time understanding the meaning of "real" vs "virtual" image.
My understanding is that for a concave mirror, the image focuses on the same side as the object so it is a real image.
For a convex mirror, the image focuses on the opposite side of the object from the mirror so it is a virtual image.
However, we can both see either real or virtual images, so how are we seeing something that focuses on the other side of the mirror in the convex case ?
I am very confused.
