3D Demonstration of Day and Night Length at Various Latitudes on Earth
2020-07-22 12:39
This GeoGebra applet constructs a 3D geometric model of the Earth-Sun spatial relationship to demonstrate how day and night lengths vary with latitude and season. Using commands such as Sphere, OrthogonalPlane, IntersectPath, and Rotate, it accurately simulates the terminator line where sunlight meets the Earth's surface and applies trigonometric functions (cosine) to calculate the ratio of daylig
