D 658 nm E 647 nm Based on the information in the table above, which of the following is the most accurate ranking of the speed of the stars from fastest toward the Earth to moving fastest away from Earth. B, D, C, A, E E, D, C, B, A C, E, A, D, B A, B, C, D, E E, A, C, D, B An important line in the absorption spectrum of stars occurs at a wavelength of 656nm for stars at rest. Imagine that you observe four stars (A-E) from Earth and discover that this absorption line is at the wavelength shown in the table below for each of the four stars. 1. STAR 2. Wavelength of Absorption line A 649 nm B 656 nm C 658 nm D 647 nm Based on the information in the table above, which of the following is the most accurate ranking of the speed of the stars from moving fastest toward Earth to moving fastest away from Earth. A=B=C=D C, B, A, D D, A, B, C Cannot be determined from the information provided. An important line in the spectrum of a typical cloud of hydrogen gas occurs at 486 nm for a cloud that is not moving relative to an observer. Imagine that you observe four different clouds of gas (A-D) from Earth and discover that this line is at the wavelength shown in the table below for each of the four clouds. 1. STAR 2. Wavelength of Absorption line A 449 nm B 460 nm C 458 nm D 447 nm
