چکیده	One of the prominent characteristics of an optical medium is the refractive index and its wavelength dependency which is called optical dispersion. If experiments and ideas could be designed in this area that could easily and with high accuracy determine the dispersion relation and refractive properties of an optical medium, it would certainly be valuable. One of the well-known and important natural phenomena whose foundation is based on the light dispersion properties is the formation of a rainbow. This eye-catching and vibrant spectrum of colors appears in the sky after atmospheric turbulence and rainfall. Based on this phenomenon, it is possible to design refractometers and dispersion measuring devices. In this paper, we present a new design for dispersion measurement using an 'inverted rain' – which refers to the creation of fine bubbles of water or any other liquid or gas within the liquid of interest. The setup for this experiment is as follows: the liquid of interest is poured into a container, and numerous bubbles are created within it. White light is incident onto these bubbles, and its refraction is simulated.
