What makes my left hand, my right hand?
Common Wrong Answers
“A shadow”
A shadow does not create a reflection or a mirrored image; it merely represents an outline or shape of an object.
“A twin”
A twin may look similar, but they are not reflections of each other in the way a mirror reflects an image.
“A camera”
A camera captures an image rather than providing a real-time reflection, so it doesn't serve the same purpose as a mirror.
