Mar 16, 2020 · With virtual images, you don't usually have this problem with focusing because the image is, by definition, on the other side of the lens. You rarely put your eye that close to the lens and the …

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 s...

The idea which helped me to differentiate between them is as follows: Image is a point of intersection of reflected/refracted rays. They might actually intersect (real image) or one might have to geometrically …
