You are presented with the question "what causes sunlight to split into different colors?" and the following answer choices: 
- bending of light rays
 - focusing a lens
 - converting electricity to heat
 - increasing electrons
 - reflections
 - heat energy
 - adding h2o
 - an electron lens

Now knowing that refracting sunlight causes sunlight to split into different colors and refraction Refraction is the bending of light rays, choose the best answer.
