Index of Refraction

Q:
We have learned through our study of physics that refraction occurs when light is bent when it enters an object with a different density than the air its travelling through.
It will slow down when it hits an object with greater density than air. But...
THE QUESTION: Will light speed up and refract if it hits something with lesser density than air? Fore example, helium? Thank you for your help.

A:
Yes, but not much since air already is not very dense.
