Why do infrared telescopes need to be placed in high altitudes or space?.
- A.To avoid interference from ground-based light sources
- B.To reduce the absorption of infrared light by the atmosphere
- C.To increase the resolution of the images
- D.To allow for larger telescope designs
Model answer
What a good answer should say
- To reduce the absorption of infrared light by the atmosphere
Explanation
Why this works
The cause is the absorption of infrared radiation by water vapor and other gases in the atmosphere. The mechanism involves the atmosphere's composition, which diminishes the intensity of infrared signals.
The effect is that ground-based infrared observations yield poor data quality. Consequently, placing infrared telescopes at high altitudes or in space enhances their ability to collect clearer infrared data.
