Reflecting and refracting diffuses ( scatter) light waves in all directions.  Because the ultra violet and blue is more dominate in the spectrum and have short waves, it is more scattered than the less dominate green, yellow, orange, or infrea red light which have longer waves that are more easily broken up.  For that reason, blue is the color in the sky.</div> <DIV ALIGN="LEFT"></DIV> <div> So, to recap,</div> <div> (A) White light enters our atmosphere,</div> <div> (B) our atmosphere defuses, filters out long wave light (green, yellow, orange, red),</div> <div> (C) ultra violet and blue short waves become dominate in the atmosphere.</div> <div> (D) The heavens appear to be blue.</div> <DIV ALIGN="LEFT"></DIV> <div> I hope you enjoyed the explanation, please visit these fine stores:</div> <div> <A HREF="http://www.vstore.com/vstorebooks/getzsales" TARGET="_top" TITLE="http://www.vstore.com/vstorebooks/getzsa"><U><IMG SRC="05c90280.gif" border=0 width="400" height="40" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></U></A> <FONT SIZE="4" COLOR="#000000" FACE="Duchess" > A superbookstore, and yes, I have the Harry Potter series.</FONT></div> <bR> <div> <A HREF="http://www.vstore.com/vstorenutrition/vitamins_ect" TARGET="_top" TITLE="http://www.vstore.com/vstorenutrition/vi"><U><IMG SRC="05d90280.gif" border=0 width="400" height="40" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></U></A> <FONT SIZE="4" COLOR="#000000" FACE="Duchess" >All the brand names at low prices.
