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

I shall refract myself, yes, I shall no longer be known as the prism.
refract a light beam
All other crystals are anisotropic: light passing through them is broken up into two plane polarized rays that travel at different speeds and refract at different angles.
A surface cannot, for instance, reflect 66% of an incoming light ray, and refract 50%, since the two would add up to be 116%.
Here, each ray was allowed to refract and reflect up to 9 times.
Separation occurs when the refractive index inside the prism varies with wavelength, so different wavelengths propagate at different speeds inside the prism, causing them to refract at different angles.
