What Does it (really) Take for an ECLIPSE?

I guess you know the drill by now. Round earth with a moon whizzing around, and the pair occasionally block sunlight from each other.  Neat stuff.

Do you want to see an actual ray diagram of that?


Well, I drew one in Adobe Illustrator, and then converted it to html.

Edit: WP Does not like custom headers in embedded html unless I pay.

Still, help yourself to a version of All-Star to make up for the blank background.

Anyway, enjoy. The ray diagram of a lunar eclipse, to scale, in PNG for now.

Congratulations. You’ve scrolled / swiped past a distance that usually takes light over 8 minutes to cover, within a time — I can only assume — shorter than that.
