So objects represented in a concave mirror are right side up past the focus point, but upside down before the focus point. When moving an object closer to the focus it appears larger and larger until it fills the frame then when it starts shrinking again it is reversed. What happens during that transition? Does the image rotate and if so what determines if it’s clockwise or anticlockwise? Does it just become a jumbled light mess that reconstitutes? I’ve been standing in front of a mirror in my bathroom moving my toothbrush back in forth like an idiot and I simply can’t wrap my head around it
