Carbon dioxide in Mars's atmosphere produces ______ in the infrared portion of its spectrum. {Ans: Absorption lines}Hot gas in Mars's upper atmosphere produces _____ in the ultraviolet portion of its spectrum. {Ans: Emission lines}Which object is likely to be the coldest? The object whose light spectrum is brightest in the {Ans: Infrared}Click "show" for the emission line spectrum, then click "choose gases" and study the emission line spectrum for neon. The neon "OPEN" sign appears reddish-orange because __________. {Ans: Neon atoms emit many more yellow and red photons than blue and violet photons}Study the graph of the intensity of light versus wavelength for continuous spectra, observing how it changes with the temperature of the light bulb. Recall that one of the laws of thermal radiation states that a higher-temperature object emits photons with higher average energy (Wien's law). This law is illustrated by the fact that for a higher temperature object, the graph peaks at __________. {Ans: A shorter wavelength}The simplified spectra for four stars is shown here. Which star has the lowest temperature? {Ans: Star D (purple line)}
