굴절계 Refractormeter
 
The refractive index of water at 20 °C is 1.33 nD.
Ice has a refractive index of 1.31 nD.
Adding sugar to pure water changes the refractive
index, depending on the amount added. Adding salt
changes the refractive index as well, but in relation to
the concentration.
This means that if pure water at 20 °C does not have a
refractive index of 1.33, it has been “polluted” with
some other material. As a rule, determining the
refractive index of a substance is a quick and reliable
check of its purity.
