This image demonstrates *parallax. The Sun is visible above the streetlight. The reflection in the water shows a virtual image of the Sun and the streetlight. The location of the virtual image is below the surface of the water and thus simultaneously offers a different vantage point of the streetlight, which appears to be shifted relative to the stationary, background Sun. This image is from Lincoln Park, San Francisco.

*There are more meanings for the term parallax.
