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 be bent toward the normal. The equation n = c / v in this case indicates, correctly, that the velocity of X-rays in glass and in other materials is greater ... WebJan 11, 2024 · To obtain robust material characteristics of the PET plastic bottle, an approximate refractive index calculation method based on the degree of polarization and phase angle is introduced.
