Question

Quizplus · Accepted Answer

The length of shadows is shortest at solar noon, so by observing the length of shadows, one can tell when it is solar noon. Sunrise and calendar may give an idea of the time of day, but not specifically when it is solar noon. A clock gives the time but not specifically whether it is solar noon or not. Graticule is an instrument used for measuring angles and distances on maps, so it is irrelevant for determining solar noon.
