Measuring refractive index of water

[Daisy]

Does anyone know any good experimental techniques of measuring refractive index of water?

Use a refractometer.

Not very helpful if you 1. Haven't got one, 2. Can't afford one.

If this is a school type of experiment that you're after then using Total Internal Reflection is a good approach because you can use readily available equipment. You might find this hyper physics link gives you an idea for a simple and cheap experiment.

Not very helpful maybe, but given the level of detail in the op...

There are several experimental techniques that can be used to measure the refractive index of water. One method is to use a refractometer, which is a device that measures the bending of light as it passes through a liquid. Another method is to use an Abbe refractometer, which measures the critical angle of light passing through a prism of the liquid. Other techniques include using a spectrophotometer or a laser interferometer. It is important to carefully calibrate and control the experimental conditions in order to obtain accurate and reliable results.
