| [Notas - Normas] Nota do Artista |
Shadow lengths change dramatically throughout the day. The length of a shadow cast on the ground is proportional to the cotangent of the sun's elevation angle – its angle θ relative to the horizon. Near sunrise and sunset, when θ=0° and cot(θ) is infinite, shadows can be extremely long. If the sun passes directly overhead, then θ = 90°, cot(θ)=0, and shadows are cast directly underneath objects.
