A Quantitative Experiment of Liquid Dispersion Using Merely a Partially Submerged Mirror and Sunlight

The refractive index (RI) is probably the single most important parameter in optical systems. Chromatic dispersion, on other hand, indicates how RI depends wavelength and central in, e.g., communication dispersion also plays an role when teaching optics due to captivating natural phenomenon of rainbow white light decomposition with a prism. In this work, we propose explore method characterize transparent liquids visible range without any dedicated equipment or device (such as prisms, goniometer, laser, detector, etc.).
