- Note that a “gray” object under a red light can reflect the same light as a “red” object under white light. If we want our color perception to remain constant under different lighting conditions, should we base perceived color on (circle one) 1) the spectrum of light reaching the eye from the object (the signal)? or X the percent of light the object reflects at different wavelengths (the reflectance)As shown two stars in the constellation Orion. Betelgeuse appears to glow red, whereas Rigel looks blue in color. Which star has a higher surface temperature? (a) Betelgeuse (b) Rigel (c) both the same (d) impossible to determineCas A SNR North Lobe Chandra ACIS image (M. Stage) region of spectrum-> 10* km/s (be sure to convert your answer to kilometers!)

The images above show real X ray data of the Cassiopeia A supernova remnant and a spectrum extracted from that data--you can see several emission lines including the silicon line near 6.6 angstroms (0.66 nm). If the emission line created by silicon normally has a wavelength of 0.6648 nm (nanometers), but is measured in the spectrum to have a wavelength of 0.6599 nm, how fast is the gas moving?
