Refractive index of aluminiu
WebRefractive index is the measurement of that angle: the ratio of the velocity of light in the air to the velocity of light in a medium through which it passes. Knowing a refractive index can help you (a) identify the medium in a liquid or (b) measure the purity and concentration of a medium in that liquid.
