/rəˌfrændʒəˈbɪlᵻdi/,

/riˌfrændʒəˈbɪlᵻdi/

Origin: Formed within English, by derivation. Etymons: refrangible adj., -ity suffix.

Etymology: < refrangible adj. + -ity suffix (see -bility suffix). Compare post-classical Latin refrangibilitas (1686 in a British source).

Optics.

1. The ability of light (or other rays) to be refracted; the degree to which light possesses this property. Now chiefly historical.

1717 J. Keill Ess. Animal Oecon. (ed. 2) 176 Rays of Light, of different Refrangibilities.

1865 J. Tyndall Heat (1870) xiii. §617 This transmutation of heat rays into others of higher refrangibility.

1879 R. A. Proctor Pleasant Ways Sci. i. 24 A gas when glowing absorbs rays of the same refrangibility as it emits.

1925 Bot. Gaz. 79 427 The factors which have been noted as influencing germination are temperature, intensity and refrangibility of light, culture media, and age of spores.

1988 Ann. Sci. 45 507 [Goethe] was..able to demonstrate that Newton's theory of light and colours is too simplistic; that there is more to colour than variable refrangibility.

2. The ability of a medium to refract light; refracting power. Now rare.
