It is possible to detect free radicals by ESR spectroscopy and imaging through the use of nitroxides. ESR stands for Electric Spin Resonance. Nitroxides trap free radicals under the skin during UV irradiation.
Infrared spectroscopy (IR spectroscopy) is the subset of spectroscopy that deals with the infrared region of the electromagnetic spectrum. It covers a range of techniques, with the most common type by far being a form of absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify a compound and to investigate the composition of a sample. For further details, see the links to the left of this answer.
Travelling through a medium that is optically less dense. Vacuum is best.

Spectroscopy is the systematic study of spectra and spectral lines. Spectral lines are used to provide evidence about the chemical composition of distant objects. So the answer to your question is through spectroscopy.. not spectrometry like the previous editor posted.
We are able to see the Moon, other Planets and even the Sun. The Sun make this possible through its light, even at night. With the help of a powerful telescope we are able to see distant galaxies, distant stars that don't exist anymore, we are seeing only its light which is still travelling.
it is lost by travelling through the floor:)
An airspeed is the speed at which an aircraft is travelling relative to the air through which it is flying.
Spectroscopy originated through the study of visible light dispersed by a prism according to its wavelength. An instrument called a spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities.
Air is the medium (if you are talking about something travelling through it).
Through sound waves travelling as vibrations through the air.
Lithgow is approximately 140km from Sydney, travelling through Richmond. Alternatively, travelling through Katoomba, it is 142km. Travel time will take well over three hours, depending on what part of Sydney one is travelling to, and the time of day one is travelling. Traffic is very heavy during peak hour.
