refract
v 1: subject to refraction; "refract a light beam"
2: determine the refracting power of (a lens)

Refract \Re*fract"\ (r?*fr$kt"), v. t. [imp. & p. p.
{Refracted}; p. pr. & vb. n. {Refracting}.] [L. refractus, p.

1. To bend sharply and abruptly back; to break off.

2. To break the natural course of, as rays of light orr heat,
when passing from one transparent medium to another of
