For these photos, I took a blue marker and painted "a lake" on a small whiteboard. On my large whiteboard, I painted a blue face. Then I held the small white board up against big white board a a right angle (right by the face), and took some photos from various vantage points.
As you progress along the three photos, I change my viewing angle from glancing to more normal to the small whiteboard. What happens seems to be like what I showed you in post two, where the lake turned from a mirror to a sheet.
Some questions that I've been pondering over
- How Can I explain the whiteboard phenomena
- How might this be the same and/or different from water phenomena, especially post two?
- Has this changed or refined my thinking about any of the previous posts?
- In what ways is the whiteboard like a mirror and not like a mirror? And Why?
And for, fun, I added these photo as well.
And just to show you that this isn't a trick with markers
And lastly, a link to a movie
More natural and contrived observations are on the way.
