Question

.The absolute refractive index of water is 1.33 and that of rock salt is 1.54.
Calculate the refractive index of i) rock salt with respect to water and ii) water with respect to rock
salt.

Answer 1

Answer:

Refractive index of rock salt with respect to air, n

r =1.54

Refractive index of alcohol with respect to air, n

a=1.36

Therefore, refractive index of rock salt with respect to alcohol, n

rr =na

nr = 1.36/1.54=1.13
