X-ray and visible light travel at the same speed in vacuum. Do they travel at the same speed in glass?

Solution

Speed of light in any material medium is inversely proportional to the refractive index of the medium. Since refractive index of glass for X-ray is less than that for visible light, an X-ray will travel at a faster speed than visible light in glass.
