 Wow, thanks guys.  That means a lot.  I just like sitting back and reading what others are talking about.  I only like to talk when I feel I have something to contribute.]]> Fri, 09 Jan 2004 13:40:27 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=1618&PID=14626&title=uv-a-b-c#14626 <![CDATA[UV - A, B, & C : jfinch wrote: Dave, you should...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=1618&PID=14612&title=uv-a-b-c#14612 Author: Adam Blundell

Dave, you should post more!

This has been an informative thread for me!

15 yrs ago, I never thought I'd need to remember anything from 2nd semester Physical Chemistry... Now I wish I'd have payed more attention .

Yeah I was thinking that as well.  However, I think it is because the glass is a liquid, but the quartz glass is still a solid, even if it is not in a crystaline form. I'm stretching my memory here as well.

Wow Adam, you're stretching my memory thin.  I'm not really sure why quartz glass is transparent to UV.  But I think there's a difference between quartz mineral (crystal) and quartz glass (non crystal).  I'd like to know myself, maybe you could ask one of those smarty pants professers where you work?

Sarnack, I was just reading about doping of metal oxides on quartz glass to reduce it's UV transparency for use in HID light bulbs (the arc tube).  So you're right, metals are added to quartz glass to reduce it's UV transparency!

Marcus, I think it's the shape of the prizm that's important, not what it's made out of.  I think most are made from leaded glass because it has better optical qualities.

Prisms can be made of anything. The important thing is how they are cut in reference to the incidence of refraction.]]> Thu, 08 Jan 2004 21:31:08 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=1618&PID=14534&title=uv-a-b-c#14534 <![CDATA[UV - A, B, & C : What are prizms made from?

Jon,

I haven't studied p-waves and s-waves for a long time but I think you're correct.  I believe the difference is because quartz is actually a solid, unlike glass.
