👉 Unscintillating is a term that describes something that has a low or negligible refractive index, which means it reflects light with less intensity than its surrounding medium. It is often used to describe objects or substances that are not highly reflective, such as glass, water, and air. The term "unscintillating" suggests that the object or substance does not absorb or scatter any light at all, making it invisible to visible light.
