1844 London, Edinb., & Dublin Philos. Mag. 25 84 The resolution of light of one colour into waves of different diffrangibility..may be subjected to the same test as the Newtonian resolution of the solar ray.
1882 C. A. Young Sun iii. 98 The refrangibility of a ray and its diffrangibility, if we may coin the word, both depend upon the number of pulsations per second with which it reaches the diffracting or refracting surface.
1934 H. V. B. Joy Synthesis Cyanine Dyes Peri-naphthothiazine Series 13 Due to its low index of refraction and small diffrangibility, infra-red light is not greatly scattered by fog or dust.
