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 ... WebThe data for the above graph is given below. As noted above, it is also available in a much more convenient Excel spreadsheet.
