What does a black-body radiation curve represent?.
- A.The relationship between temperature and emitted wavelength
- B.The relationship between mass and luminosity of a star
- C.The absorption spectra of different elements
- D.The distance of a star from Earth
Model answer
What a good answer should say
- The relationship between temperature and emitted wavelength
Explanation
Why this works
A black-body radiation curve illustrates how the intensity of radiation emitted by a perfect black body varies with wavelength at different temperatures, showing that higher temperatures lead to shorter peak wavelengths.
