Which of the following lists astronomical distance measurement techniques in order of the maximum distance to which they are useful?
A) parallax, spectroscopic parallax, Hubble's law, Type Ia supernova
B) parallax, Cepheid variables, spectroscopic parallax, Hubble's law
C) parallax, Cepheid variables, Type Ia supernova, the Tully-Fisher law, Hubble's law
D) parallax, Cepheid variables, Type Ia supernova, Hubble's law

Question

Quizplus · Accepted Answer

Parallax is used for the closest stars, Cepheid variables for intermediate distances within our galaxy and nearby galaxies, Type Ia supernovae for farther galaxies due to their standard brightness, and Hubble's law for the most distant galaxies by relating their redshift to distance.
