Wolfgang Christian and
The Noon Shadow model shows the geometry of the shadow cast by a gnomon at noon. Users can change the orientation of the gnomon as well as its latitude. The height of the gnomon and its shadow length are displayed in Earth radius units. It is a supplemental simulation for an article by Barbara Rovsek "Calibration of a Horizontal Sundial" in the The Physics Teacher 48 (6), 397-400 (2010).
