[ou.02]the ozone layer in earth's atmosphere absorbs ultraviolet radiations. which of these is the best location to place a telescope used to observe ultraviolet radiations from stars?

space
mountain
top of building
high-flying aircraft

Option A, Space

Explanation:

It is observed that the humidity(presence of water droplets) in the atmosphere filter out the infrared and ultraviolet radiations from the electromagnetic spectrum. Thus, for having a clear view of ultraviolet radiations it is better to place  the telescope at a dry place (which is devoid of humidity).  

Air at mountain's top is cold and dry and hence telescope at this location gives a better clarity. A telescope placed in a high-flying aircraft will give a clarity better than that of telescope placed at a mountain. Space is devoid of air and hence it shall give the best clarity of all the given options.

Thus, option A is correct
