SpletPred 1 dnevom · The resulting sound wave is amplified by an acoustic resonator and detected by a microphone. This effect is called “non-radiative relaxation”. As a result, the sample gas heats up minimally and then returns to its equilibrium temperature. Since the optical excitation is periodic, the heat input also repeats at the same frequency. SpletBy trace gas I mean a gas with a mixing ratio of less than 20 ppm in the atmosphere. Defend your choice. Use information from this lesson as well as other sources (credit them, please!) to describe the qualities of this gas that make you think that it is the most important trace gas.
