What objects refract light?
Elena AntonovaAny substance that allows any light radiation frequencies to pass through it will refract the light beam.
As an interfacial phenomenon, "refraction" is the effect that happens when light passes between two substances with different refractive indices; it does not occur within a material itself. Refracting interfaces can occur between similar phases (gas, liquid, or solid) or between different phases.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
