WebThe refractive index of X-rays is slightly less than 1.0, which means that an X-ray entering a piece of glass from air will be bent away from the normal, unlike a ray of light, which will … WebRefractive index Light will travel through different types of materials at different rates. When light travels through one material (such as air) and into another (such as water), the light is refracted. It appears bent. For instance, when you put a pencil in a glass of water and view the glass from the side, the pencil will look bent.
