Question

A tank holds a layer of oil, of thickness T_0= 1.65 m, that floats on a layer of syrup of thickness T_s= 0.830 m, as shown in the figure. Both liquids are dear and do not mix together. A light ray, originating at the bottom of the tank at point P, crosses the oil-syrup interface at a point 0.900 m from the axis. The ray continues and arrives at the oil-air interface, 2.00 m to the right of P and at the critical angle. What is the index of refraction of the syrup?
