Why do longer wavelengths of light refract less?

The energy crests of the waves are further apart.
Explanation:
When the crests encounter resistance the wave is bent or refracted.
When the crests are closer together the crests encounter resistance "sooner" and are refracted faster.
When the crests are further apart the crests encounter resistance "later" and so are refracted less.
