FLAT EARTH - OPTICS ON A FLAT EARTH
Geometrical demonstration of what horizons are on a flat planar surface and how they would appear.
Shows why objects are cut off bottom first and appear to visually disappear into the surface.
10 miles model with building at 7.5 miles geogebra.org/geometry/vDdWfZmq
50 miles to Sears Tower geogebra.org/geometry/tkgnqgb4
Part 1: How Does The Eye or Camera See? @0:10
Part 2: Angular Size and The Eye @0:44
Part 3: What Determines Angular Size? @1:16
Part 4: Angular Separation and Angular Resolution @2:42
Part 5: How Angular Resolution Creates an Apparent Horizon @3:41
Part 6: The Invisibility Of The Bottom Of Objects @4:43
Part 7: Why Objects Appear To Go Lower @5:41
part 8: Why Doesn't The Top Disappear Like The Bottom? @6:03
