Относительный показатель преломления:

n = n2/n1, где n2 = 1 - абсолютный показатель преломления воздуха, n1 - жидкости, тогда:

n1 = n2/n

В то же время:

n = sinα/sinβ, где α = 90 - 60 = 30° - угол падающего луча по отношению к вертикали, а β = 90 - 30 = 60° - угол преломлённого луча. Тогда:

n1 = n2/(sinα/sinβ) = n2*sinβ/sinα = 1*sin60°/sin30° = (√3/2)/0,5 = √3*2/2= √3 = 1,73

Ответ: 1,73.
