/taɪˈθɑnɪk/

Origin: From a proper name, combined with an English element. Etymons: proper name Tithonus , -ic suffix.

Etymology: < the name of Tithonus (classical Latin Tithōnus , ancient Greek Τῑθωνός ; in classical mythology, husband of Aurora (Eos), who was granted immortality but not eternal youth) + -ic suffix, so called with allusion to the fact that the visible effect of such rays on photographic paper fades over time. Compare tithonize v.

Photography. Now historical.

In the terminology of John William Draper: designating the largely invisible light rays or components of light which cause chemical effects on photographic films, etc.; of or relating to such light (now recognized to be chiefly ultraviolet) or its effects. Cf. actinic adj. 1, chemical ray n. at chemical adj. and n. Compounds 3.
