Question: When two plane mirrors are parallel, such as on opposite walls in a barber shop, multiple images arise because each image in one mirror serves

When two plane mirrors are parallel, such as on opposite walls in a barber shop, multiple images arise because each image in one mirror serves as an object for the other mirror.
