Question

What can be used to bend light?

Answer 1

Answer:

Snell's law describes how light bends. Light is also bent when traveling past massive objects - look into "gravitational lensing" if you are interested. Light can be effectively bent into a parabolic path using materials that have changing index of refraction. This is done in fiber optics using "graded-index fiber."
