The Thin Border between Light and Shadow
Guglielmino, M.; Gratton, L. M.; Oss, S.
Physics Education, v45 n4 p378-381 Jul 2010
We propose a simple, direct estimate of the Sun's diameter based on penumbra observation and measurement in a two-level approach, the first for middle-school pupils and making use of simple geometrical arguments, the second more appropriate to high-school students and based on a slightly more sophisticated approach. (Contains 5 figures.)
