ResearchFlatMoon | The Radius of the Earth | Al Biruni @ResearchFlatMoon | Uploaded July 2021 | Updated October 2024, 3 hours ago.
Following up on our last video where we found the height of a mountain using the tangent function and a little algebra. Today we use that information to determine the radius of the earth and have a discussion of the effects of refraction.
Upon review I noticed a slight error in my discussion of refraction. What I was discussing was the standard refraction of 7/6 R. Given a determination of the REFRACTED radius, to get the true radius you would divide by 7/6 or MULTIPLY by 6/7. I accidently said divide by 6/7. Sorry for the confusion.
