Space-21-mcq-02. For a red-shifted absorption lines, choose the strongest evidence answer about (Physics only) Describe red shift as an increase in the observed wavelength of light from a galaxy. Focus vocabulary: observation spectrum signal data measurement inference support pattern conclusion.
- A.space-21-mcq-02 evidence: red-shifted absorption lines correctly supports (Physics only) Describe red shift as an increase in the observed wavelength of light from a galaxy by using observation, spectrum, signal, data in Red-shift and evidence for an expanding universe.
- B.space-21-mcq-02 orbitrotation error: this swaps orbit with rotation and misses evidence reasoning.
- C.space-21-mcq-02 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
- D.space-21-mcq-02 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.
