Optical and radio telescopes are built on the ground, but X-ray Astronomy is possible only from satellites orbiting the earth because
  • a)
    Satellites orbiting the earth make use of interstellar effects
  • b)
    Atmosphere reflects X-rays horizontally so they don’t reach the earth
  • c)
    Atmosphere absorbs X-rays, while visible and radio waves can penetrate it.
  • d)
    Atmosphere reflects X-rays away from earth
Correct answer is option 'C'. Can you explain this answer?
