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.
