Any substance that allows any light radiation frequencies to pass through it will refract the light beam.


"Refraction" is the effect that occurs when the light passes between two substances with different refractive indices. It is an interfacial phenomenon and it does not happen within a material itself.
The refracting interfaces may be between similar phases (gas, liquid, solid), or different ones.
