Explanation:

We know that x = 90º because we have a critical angle, in which the angle refracts. sin (x) = sin (90º) = 1, thus m*sin(y) = n*sin(x), hence m = 1 / sin(48.2) is our refractive index. Hence, its refractive index is 1.341424808.

m \: sin \: x = n \: sin \: y \\  \\ m \: sin \: 90 °= sin(48.2) \\  \\  m =  \frac{1}{sin \: (48.2) }  \\  \\  = 1.34
