"It [love] delights not in undue disclosing of brethren's failings."-Leighton: On 1 Peter iv. 8. sin, as; expect, Xenophon, exist. ph = f "Gliding and lapsing in an undulant dance." Sir H. Taylor: St. Clement's Eve , ii. 2. IMG:content-0094.png:[blocks in formation] 3. Surg .: A certain motion of the matter of an absce when pre ed, which indicates its fitne for opening. 1. Length of an undulation : Acoustics: The distance which sound travels dur- ing a complete vibration of the body by which it is produced. 2. Point of undulation : [SINGULAR-POINT.] tun-du-lā-tion-Ist, s . [Eng. undulation ; -ist .] One who supports the undulatory theory of light. un-du-lāt-Ive, adj . [English undulat (e); ive.] Undulating, undulatory. un-du-lā-to-, prep . [UNDULATE.) Undulated, undulating, waved on the margin. undulato-rugose, a. Bot.: Rugose or rugged, waved. ( Loudon .) undulato-striate, a . Bot.: Having elevated lines wavy in direction. un-du-lā-tõr-ý, adj . [Eng. undulat ( e ); -ory.] Having an undulating character; moving in the manner of a series of waves; rising and falling like waves; pertaining to such a motion. "The undulatory motion propagated along the body."_ Paley: Nat. Theol ., ch. xvi. undulatory-theory, s . Optics: The generally accepted theory which traces light to vibrations set up and transmitted as waves in an invisible medium termed the lum in- iferous ether. This, it is a umed, is (sensibly) imponderable, and almost infinitely elastic, and fills all space, pa ing freely through the pores or between the atoms of bodies as the wind does through the trees, but having its motions, in a some- what analogous manner, hindered or modified thereby, and thus accounting for the retardation which is the principal factor in producing Refrac- tion (q. v.) Luminous bodies are believed to be (and in the case of heated luminous bodies are known to be) in a state of intense molecular vibra- tion, and these succe ive impulses communicated to the ether give rise to succe ive waves of radiant energy, whose effects on other bodies depend upon their rate, as the pitch of a sound does. The slower periods apparently cause heating effects only; more rapid impulses produce luminous and chemical effects as well, and energetic chemical action is exerted by waves far too rapid to produce lum in- ous impre ions. Within the luminous range each rate produces on the normal retina the sensa- tion of one given color only, while a proportion of all periods mixed produces that of white. In the phenomena of Reflection, Refraction, Dispersion, and ordinary Interference, there is nothing to define the direction the actual ethereal i bra tions that these must be at right angles to the path of the fig .) (Shakesp.: Sonnet 3.) ray, which again implies that the ether, rare and subtle as it is, must have the chief distinguishing quality of a solid, or resemble a thin but solid jelly rather than a fluid. This is believed to be the case, and the ether is also believed to be the medium through which electricity and other forms of energy are transmitted. The Undulatory Theory is usually ascribed to Huyghens, but was firmly established by the convincing experiments and reasoning of Young and Fresnel. Newton adopted the Corpus- cular Theory, but in the second edition of his Opticks he added "queries," showing that later he was very strongly disposed to adopt the other. *un-dull', v . t . [Pref. un- (2), and Eng, dull .] To remove dulne or obscurity from; to clear, to purify. IMG:content-0095.png:[blocks in formation] un'-du-lous, a . [UNDULATE.] Undulating.
