WebDust reddens starlight because itANS: preferentially affects light at visible and shorter wavelengths. What is the most likely explanation for the dark area in the figure shown? ANS: It is a region with thick dust blocking the starlight coming from behind. Sitting in a 100°F hot tub feels much hotter than standing outsidillustrates e on a 100 ... WebDust reddens starlight because ita.re-emits the light it absorbs at red wavelengths. b. emits mostly in the infrared due to its cold temperature. c. is made mostly of hydrogen, which produces the red H-alpha emission line.d.preferentially affects light at visible and shorter wavelengths. e. primarily moves away from Earth.

Webstarlight passed through. Dust and air in the atmosphere also dims and reddens starlight... The longer the path length the starlight traverses through the atmosphere, the more it is dimmed. Thus, a star close to the horizon will be dimmed more than one close to the zenith. The path length through the atmosphere is known as the air mass. WebDec 20, 2015 · It is similar with interstellar dust, only the dust particles are much smaller than typical terrestrial smoke particles so the color effects are greater. Those small … WebA starlight reflected by dust, B a star behind invisible interstellar gas, and C an emission nebula. A. The overall shape of the spectrum is the similar to that of the star: a continuum ... If the brightness decreases by a factor of 100 because of dust, and we cannot detect the dust, then we will estimate that the star is 10 times farther away ... iphone 15 lidar
