To Measure the Refractive Index of Water.

 

In an experiment to measure the refractive index of water, the following values were obtained:

 

Real Depth / cm

17.3

14.2

12

9.1

Apparent Depth / cm

13.1

10.7

9.0

6.8

 

Use these data to find an average value for the refractive index of water.
