Therefore, only one line of lati- tude on the Earth's rotating surface can receive radiation at right angles, while the rest receive varying oblique (sharp) angles ( Fig. ). As we can see from Figure and c, solar 66 2 . 1. energy that strikes Earth at a nearly vertical angle renders more intense energy but covers less area than an equal amount striking Earth at an oblique angle. Eq The intensity of Insolation received at any given latitude ua tor Sun can be found using Lambert's Law, named for Johann Lambert, an 18th-century German scientist.
