for the quartz. Using a Snell's Law, we can write the critical angle that is, a fantasy is equal to sign in war. So for perfecting next off water divided by reflecting this cough quartz, which is substituting Raelians 1.333 for water divided by the refracting liftoff courts, which is 1.458 This gives also the critical ago, for course, to be 66.1 degrees for police styrene. We have a critical angle that is a fantasy. Easy call the signed in Warsaw for the reflecting next off water divided by the frightened. That's a full list. I mean substituting values here, reflecting this award. A 1.333 divided by reflecting Knicks off polystyrene one point 49 This gives us a critical angle off a 63.5 degrees. Really for any CEO for sodium chloride, we can write to pick a lingle that is equal to sign in Warsaw for the perfecting this off water do right by reflecting Knicks off N A a. C l. Substituting values. We have 1.333 for water, divided by 1.55544 for any cell. This gives of the critical angle off 59.7 degrees
