Question

Quizplus · Accepted Answer

When an observer focuses on a point at a middle distance, objects that are closer than this point of fixation appear to move backward relative to the direction of motion. This phenomenon is due to the relative motion perceived by the observer, where closer objects seem to move in the opposite direction of the observer's actual movement.
