1/17/2024 0 Comments Earth is not flatThat was thanks to scientists, philosophers and mathematicians who, as early as around 600 B.C., made observations that Earth was round. onward believed that the Earth was flat.” According to historian Jeffrey Burton Russell, “no educated person in the history of Western Civilization from the third century B.C. If you are interested in reading more about snell's law of refraction, you should check out our Snell's law calculator here.There’s just one problem: It’s almost certain that in the 1490s, nobody thought the earth was flat. That's why, when you are calculating the obstructed height of an object, the distances you see maybe a bit different from the observed ones! That means that some photons from the object that would usually hit the ground can bend around the Earth's surface and reach your eye, so the heights and distances as shown in the picture above may seem to be different. For example, refraction can happen when light hits a pocket of cold air or a hot draft of rising air.Īs the ray of light bends slightly, it changes direction. When light travels through a medium that is not perfectly uniform, such as air, it bends or refracts. Of course not! It just means that our calculator doesn't account for the phenomenon of refraction. Why does this happen? Does it mean the Earth is flat and doesn't curve at all? a real-life scenario, our calculator might be slightly wrong in some cases. You might find that if you were to test our calculator vs.
