Skipping Stones of Light: Grazing Incidence X Ray Telescopes

You can't reflect an X-ray with a normal mirror. Because these high-energy waves would pass right through a standard telescope, scientists use nested, ultra-smooth shells to skip them like stones on water. This grazing...

Sample Question 1
Why can't conventional "normal incidence" mirrors (like those in home bathrooms) be used to focus high-energy X-rays?

X-rays are too cold to reflect

X-ray photons are absorbed by or pass through the mirror material

X-rays only reflect off liquid surfaces

The silver coating on mirrors turns X-rays into radio waves

X-rays move too slowly to be reflected

Sample Question 2
Grazing incidence relies on the principle of "Total External Reflection."

True

False
