- B.Infrared telescopes detect visible light, while X-ray telescopes detect radio waves.
- C.Infrared telescopes detect gamma rays, while X-ray telescopes detect ultraviolet light.
- D.Infrared telescopes detect sound waves, while X-ray telescopes detect electromagnetic waves.
Model answer
What a good answer should say
- Infrared telescopes detect heat emissions, while X-ray telescopes detect high-energy radiation.
Explanation
Why this works
Infrared telescopes and X-ray telescopes serve different purposes in astronomical observations. Infrared telescopes detect heat emissions from celestial bodies, allowing us to observe cooler objects like dust clouds and distant galaxies.
In contrast, X-ray telescopes detect high-energy radiation emitted by extremely hot objects, such as black holes and supernova remnants. This distinction is crucial for understanding various astrophysical phenomena, as each type of telescope reveals different aspects of the universe.
