Abstract This paper construed to study the important optical properties of Zamzam water, optical absorption and transmission had been studied at different wavelengths (300 – 800) nm, the refraction index was determined at 589.8 nm, another important optical properties had been also calculated such as specific refraction, reflectance, finesse coefficient, permittivity and polarizability per unit volume, the paper also study important properties that is PH and ppm. All of these were compared with three samples of water which are; tap water, distilled water and magnetic water which has been prepared by an electrical coil of 200 Gausses. The results show that the optical absorption of Zamzam water is the largest compared with other sample at different wavelengths, specially at 5000 nm, and the transmission is the smallest, on the other hand the refractive index of Zamzam water is 1.3345 at 589.8 nm that is the largest compared with other sample, the PH for Zamzam water is 6.55 and ppm is 186. It has been concluded that Zamzam water has special optical properties compared with other sample. This lead to the possibility to use Zamzam water as an optical liquid which has unusual properties.
