Exam-style question
Try this first
Wien peak: Select the conclusion from a shorter peak wavelength in a stellar spectrum. This tests Relate parsec to parallax angle. in Absolute magnitude.
- A.Wien peak answer: A shorter peak wavelength indicates a higher surface temperature.
- B.Wien peak distractor: It proves the star is closer.
- C.Wien peak misconception: It halves the Hubble time.
- D.Wien peak off-scope: It increases telescope focal length.
Model answer
What a good answer should say
- The correct option is Wien peak answer: A shorter peak wavelength indicates a higher surface temperature.
Explanation
Why this works
It is correct because it applies Absolute magnitude evidence to Relate parsec to parallax angle.. The other options are incorrect because they swap in a different astrophysics measurement, telescope property or cosmology idea.
