Question

Why does a mirror appear to reverse left and right but not up and down? in student and science term

Answer 1

In simple terms, the reason a mirror appears to reverse left and right but not up and down is because mirrors work by reflecting light. When light hits a mirror, it bounces off and creates a reversed image of whatever is in front of it. Left and right are reversed because the mirror flips the image horizontally, but up and down are not reversed because the mirror does not flip the image vertically. This means that top and bottom stay in the same position in the reflected image.
