How does the temperature of a star affect its absorption spectrum?.
- A.It does not affect the spectrum at all
- B.Higher temperatures lead to more absorption lines
- C.Lower temperatures result in fewer absorption lines
- D.Temperature influences the intensity and position of absorption lines
Model answer
What a good answer should say
- Temperature influences the intensity and position of absorption lines
Explanation
Why this works
The temperature of a star affects the absorption spectrum by influencing both the intensity and position of the absorption lines. Higher temperatures can cause more energetic transitions, altering the spectrum observed.
