Physics Problem Help?
A jeweler must decide whether the stone in Mrs.Smigelski’s ring is a real diamond or a less-precious zircon. He measures the critical angle of the gem and finds that it is 31.3. Is the stone really a diamond or just a good imitation?
(n of diamond=2.41)(n of zircon=1.92)
i think you’re meant to use the snell’s law equation if that helps
thanks!
sin(critical angle)=1/n
n=1/sin(31.3°)=1,925
so it’s zircon
