ground-based infrared telescopes reside at high altitudes in dry climates. what explains the location for these infrared telescopes?
a) these telescopes must make observations above much of the water vapor in the atmosphere because water can block infrared rays.
b) these telescopes do not function at warmer surfaces since infrared waves emit heat.
c) these telescopes must be away from interference from surface radio stations.
d) these telescopes must be closer to the objects they are observing.
