Question

An ideal infinite plane mirror translates parallel to its own surface without rotating while a fixed point object remains in front of it. Which statements are correct?

G1 Physics · Accepted Answer

Translation parallel to an infinite plane does not change the plane itself. Therefore the image of a fixed object remains at the same geometrical point.
