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.
p. of refringere; pref. re- re- frangere to break: cf. F.
r['e]fracter. SEe {FRacture}, and cf. {Refrain}, n.]
1. To bend sharply and abruptly back; to break off.
[1913 Webster]

2. To break the natural course of, as rays of light orr heat,
when passing from one transparent medium to another of
different density; to cause to deviate from a direct
course by an action distinct from reflection; as, a dense
medium refrcts the rays of light as they pass into it from
a rare medium.
[1913 Webster]

  • REFRACT | English meaning - Cambridge Dictionary
    When a laser beam is focused onto a dielectric sphere, the rays incident on the particle are reflected and refracted at the surface The waves are refracted according to the ordinary refraction law deduced for non-moving magnetoactive plasmas

  • Refraction | Definition, Examples, Facts | Britannica
    Refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed For example, the electromagnetic waves constituting light are refracted when crossing the boundary from one transparent medium to another because of their change in speed
  • Refraction of light — Science Learning Hub
    A rainbow is formed when light enters each water droplet, and the different colours bend (refract) at slightly different angles They reflect off the inside of the drop before refracting again as they leave The shorter wavelengths refract more
