The correct answer to the question is 0.978.
CALCULATION;
As per the question, we are asked to calculate the refractive index of water with respect to alcohol.
The refractive index of any medium 2 with respect to medium 1 is calculated as -
Here, is the refractive index of medium 2 with respect to air
is the refrcative index of the medium 1 with respect to air
The refractive index of the water with respect to air is = 1.33
The refractive index of the alcohol with respect to air is = 1.36
Here, we have taken a common value of refractive index of alcohol with respect to air.
Hence, the refractive index of water with respect to alcohol is calculated as-
=
= 0.978 [ans}
