How far is the horizon over water
Did you know?
Due to atmospheric refraction the distance to the visible horizon is further than the distance based on a simple geometric calculation. If the ground (or water) surface is colder than the air above it, a cold, dense layer of air forms close to the surface, causing light to be refracted downward as it travels, and therefore, to some extent, to go around the curvature of the Earth. The reverse happen… Web4 apr. 2024 · Kies Horizon Over Water stockfoto's, afbeeldingen en royalty-free beelden uit iStock. Ontdek stockfoto's van hoge kwaliteit die u nergens anders vindt.
