What happens to the black-body radiation curve as the temperature of the black body increases?.
- A.The curve shifts to longer wavelengths
- B.The curve shifts to shorter wavelengths
- C.The curve remains unchanged
- D.The area under the curve decreases
Model answer
What a good answer should say
- The curve shifts to shorter wavelengths
Explanation
Why this works
As the temperature of a black body increases, the peak of the black-body radiation curve shifts to shorter wavelengths, indicating that more energy is emitted at higher frequencies.
