How does light travel faster in optically rarer medium?

Is it because that there are less molecules within one unit volume in rarer medium that light is able to travel through it easier?

Welcome to PF Anitha!

Light travels more slowly in any medium other than a vacuum. It is rather complex, actually. There is a very good FAQ on this.
