Here are the likely answers based on the concepts of redshift and blueshift in astronomy:
-
Spectrum of stationary galaxy vs. galaxy in motion (stationary distance):
Answer: It is exactly the same.
(When both galaxies are stationary relative to each other, their spectra do not shift.) -
Spectrum of stationary galaxy vs. galaxy in motion (Farther away):
Answer: The spectrum shifts to the right, towards red.
(If the galaxy in motion is moving away, this results in redshift.) -
Spectrum of stationary galaxy vs. galaxy in motion (Closer):
Answer: The spectrum shifts to the left, towards blue.
(If the galaxy in motion is moving closer, this results in blueshift.) -
Analyze Spectral Shift: Galaxy 1:
Answer: red shift
(If the galaxy is moving away, it will exhibit a redshift.) -
Analyze Spectral Shift: Galaxy 2:
Answer: blue shift
(If the galaxy is moving closer, it will exhibit a blueshift.) -
Analyze Spectral Shift: Galaxy 3:
Answer: no shift
(If there is no change in distance, the spectrum shows no shift.) -
Analyze Spectral Shift: Galaxy 4:
Answer: red shift
(If the galaxy is moving away from us, it will exhibit redshift.)
