while a simple concave mirror projection does not?Hi,
I'm really not sure where does this question go, but perhaps this is as good a place as any...
If not, then I would appreciate a referring to the right place.
So, I have encountered this nifty, decades old, illusion created by combining two concave mirrors : http://dev.physicslab.org/Document.aspx?doctype=3&filename=GeometricOptics_RealImages.xml
I understand how it works and I kinda assumed that all mirrors which have a certain focal point would act similarly so their image projection would look like the object is actually there.
I have googled a bit (youtubed actually ) and have encountered some videos on the matter:
None comes even close to the quality of said illusion, and I wonder why is that?
Same goes for those experiments with a lens (a long metallic rack in which you move a needle closer and farther from a focusing lens).
In theory it should all work, but...Thank you very much!
