Explain what parallax is Give an example how parallax occurs Locate an image in a plane mirror Optics Parallax Parallax is a difference in the apparent position of an object due to the motion of an observer. Copyright Optics Paraxial (first order) approximationMonochromatic aberration (Seidel and wave aberrations)Chromatic aberration (Longitudinal, Transverse) s law, FermatParaxial (first order) approximationMonoch Parallax is the apparent displacement of an object against the background when seen from two different perspectives.. Definition of Parallax. To measure the distance to a star, astronomers measure the parallax shift of the star using 2 points of view that are as far apart as possible-at opposite sides of Earth’s orbit..
