Space Forum / Space Flight / January 2006How far can you see into LOx?
At http://radio.weblogs.com/0101365/2003/11/12.html is shown the blueness of a test-tubeful of LOx, and its absorption spectrum. What about a light path of several metres? When you looked down into such a thickness, how far could you see? If a swimming pool were filled with it, and had lights in its walls, would you expect them to be visible from above? --- Graham Cowan, former hydrogen fan http://www.eagle.ca/~gcowan/Paper_for_11th_CHC.html boron as energy carrier: real-car range, nuclear cachet > What about a light path of several metres? > When you looked down into such a thickness, > how far could you see? > If a swimming pool were filled with it, > and had lights in its walls, > would you expect them to be visible from above? I recall that LH2 is as transparent as water, from internal footage of Saturn IB and V tankage in orbit. The image in this link suggest visibility in LOX should be at least a few meters. http://www.rsbs.anu.edu.au/ResearchGroups/PBE/Oxygen/O2_1 _PhysicalProperties.htm --Damon > > What about a light path of several metres? > > When you looked down into such a thickness, [quoted text clipped - 4 lines] > > I recall that LH2 is as transparent as water, ...

What's the scale? The other picture link again: http://radio.weblogs.com/0101365/2003/11/12.html --- Graham Cowan, former hydrogen fan Boron fire good. http://tinyurl.com/4xt8g |
