View source for infrared and ultraviolet


It's easy to talk about visible light, or about radio, or about the electromagnetic spectrum as a whole, but what about the other major regions of the spectrum?

* infrared
** A first try: le me'i xunre se dirce or, by extension,  mecyxunseldi'e -- [[RobinLeePowell|RobinLeePowell]]

*** Um. I translate that as "less red radiation". Not "less-than-red radiation", which would require the ''me'i'' to describe a property of ''xunre'' somehow - a red light that diminishes in brightness would emit ''le me'i xunre se dirce''.
* ultraviolet

* x-rays
** The name "x-ray" is purely conventional. I don't have any better idea than ''xy. zei gusni''. ''mi'e [[jezrax|jezrax]]''

(You really have to use ''boxna'' (pleeeeease no "red" or "violet" calques!):

''gusni xe boxna barda (cmalu) se dukse fi lenu viska narkakne'' or just

''gusxembonbra(cma)du'e'' for short...

* Why is it a calque to say something involving "red" or "violet"? If I describe infrared as "beyond-red light" (bancu xunre gusni), isn't it correct?
** I like ''bacyxungu'i'' and ''bacyblagu'i''. They're a little vague but seem clear enough for everyday use. Scientists will definitely prefer ''boxna'' when being technical. ''mi'e [[jezrax|jezrax]]''

* Incidentally, your tanru doesn't work (''gusni xe boxna barda dukse'' is a kind of ''dukse'' - not something excessive, but the excess itself) and if you can come up with a seljvajvo place structure for ''gusxembonbradu'e'', more power to you. --[[rab.spir|rab.spir]]

...but wouldn't it be a good use for our MEX

notation if we were to specify the actual range of wavelengths that define these

terms? e.g.

* near UV  ''boxna fu su'evo decmiktre''
* infrared ''boxna fu su'ozepivo decmiktre'' (though i am used to using Angstroms, it seems silly to talk about 4000 or 7400 of a ten-billionth of a meter in Lojban)

** So why do you talk about 7.4 of a ten-millionth of a meter rather than 740 billionths? I think using nm for wavelengths of light around the visible range is well established. (My real quibble is with the non-power-of-10^3 used here: 10^-7 seems like an illogical base when 10^-9 or 10^-6 will do -- and require only one prefix rather than two.) That would then become ''su'evonono navytre'' and ''su'ozevono navytre'', respectively. mi'e filip
* Are you looking at the same ''[[gimste|gimste]]'' I am? Mine gives wavelength ''velbo'a'', frequency ''xelbo'a'', so you want ''fo'' not ''fu''. ''mi'e [[jezrax|jezrax]]''
