Why do X-ray telescopes need to be placed above the Earth's atmosphere?.
- A.X-rays are too energetic for ground-based observation.
- B.X-rays are absorbed by the atmosphere.
- C.X-rays can only be detected in space.
- D.X-rays require larger apertures for collection.
Model answer
What a good answer should say
- X-rays are absorbed by the atmosphere.
Explanation
Why this works
X-rays are absorbed by the atmosphere, preventing ground-based telescopes from effectively observing X-ray emissions from celestial objects. By placing X-ray telescopes above the atmosphere, they can collect these high-energy wavelengths without atmospheric interference, leading to better observational data.
