Which of the following accurately explains why the telescopes that detect invisible waves, such as infrared, microwaves, and gamma rays, are placed in space?
There are not enough places on land to build observatories that hold large telescopes.
All telescopes must be placed in space. There are no telescopes on land.
The waves in the electromagnetic spectrum are all too small to be detected by telescopes on land. Therefore, in order to see any electromagnetic radiation, telescopes must be placed in space.
Most radiation reaching Earth from space is blocked by the atmosphere. Therefore, some telescopes must be placed above the atmosphere.
The correct answer is:
Most radiation reaching Earth from space is blocked by the atmosphere. Therefore, some telescopes must be placed above the atmosphere.
Explanation: Earth’s atmosphere absorbs and scatters many types of electromagnetic radiation, including infrared, microwaves, and gamma rays. By placing telescopes in space, scientists can avoid this interference and obtain clearer, more accurate data from these invisible waves. This allows for better observations of astronomical phenomena that emit these types of radiation. If you have more questions or need further clarification, feel free to ask!
