Help physics plz.....?

A light ray in air hits a piece of quartz at

a 39.0 deg angle. Inside the quartz, the

light slows down to 2.06*10^8 m/s. At

what angle does the light travel in the

quartz? (Hint: find n.) I don't know this.

    find refractive index, n, using n=v/c

    then use n = sin(i)/sin(r) to find r.
