A mirror is made from a sheet of glass with reflective material applied to one side of the glass. Designed to reflect lights, mirrors are used everywhere from making sure we scrub behind out ears in the morning, to helping us reverse around corners without crashing into a wall. But what are mirrors exactly? A mirror is like an old fashioned transparency photograph viewed the wrong way around. A mirror doesn't reverse left and right, it reverses back to front. Writing appears back to front in a mirror because we present it back to front! Go on; have a go writing BUM the wrong way around in front of a mirror! Wondered where the glass in the mirror comes from?
