Re: [Phys-l] Transparency

[Bernard Cleyet <bernardcleyet@redshift.com>]

Another related phenomenon is a pile of plates*.  I was reminded of  
this when I saw a number of rolls of what I thought was aluminized  
plastic film at RAFT**.  I unrolled a layer and found it was  
transparent, while the roll was mirror silver;  sufficiently specular  
to see reflected objects.  At home I observed a cover glass***, quite  
transparent, a stack of 50 was a poor quality mirror with a little  
transmission when interposed between a bright lamp

* Normally used to separate s and p waves.  Before high quality  
lithography,  selenium pellicles for the infrared.

*** plastic tissue culture cover slips (from RAFT).   I didn't find  
my box of microscope slides.
