Blackbody curve: Choose the correct use of a blackbody spectrum. This tests Use Wien's law to estimate surface temperature. in Temperature and black-body radiation.
- A.Blackbody curve answer: Its peak wavelength can estimate surface temperature.
- B.Blackbody curve distractor: It counts binary companions directly.
- C.Blackbody curve misconception: It replaces all distance measurements.
- D.Blackbody curve off-scope: It gives diffraction angle without aperture.
Model answer
What a good answer should say
- The correct option is Blackbody curve answer: Its peak wavelength can estimate surface temperature.
Explanation
Why this works
It is correct because it applies Temperature and black-body radiation evidence to Use Wien's law to estimate surface temperature.. The other options are incorrect because they swap in a different astrophysics measurement, telescope property or cosmology idea.
