The effect of Faraday Effect has been discovered for more than a century. Since then, various related research and application development is carried out rapidly for utilizing such effect. However, came across varies sources of references, there is not one concrete value for the verdet constant for a specific substances. The purpose of this experiment was to determine the verdet constant of water by using dilution method and comparing it to the references value. By proving such method is applicable for finding verdet constant, this method can be further extend to apply to other substances given under the suitable situation. Before the experiment of the Faraday rotation, a magnetic field calibration is carried out to justify the different of magnetic field at the measured position and the effect happened position. After that, another measurement is carried out select the suitable frequency range to avoid extra signal adding to the final reading. After these 2 pre-experiment steps were done, the Faraday Effect experiment is starting by measuring verdet constant of 5 different concentration against angle change, and from the result, we can have the verdet constant of water at 0 concentration. The finding of this experiment gets the verdet constant close to the references value with minor different. And the inaccuracy of this experiment is discussed in the later chapter which mainly due to the limited resources available. However, the dilution method is proved to be a successful method to determine the verdet constant.
