There is an inverse relationship between the sun's altitude and shadow length. When the sun is high in the sky (high angle of elevation), shadows are short. When the sun is low on the horizon (low angle of elevation), shadows are long. At the exact moment the sun is directly overhead (90°), objects cast no shadow.
