Exam-style question
Try this first
Which law relates the temperature of a black body to the peak wavelength of its emitted radiation?.
- A.Stefan-Boltzmann Law
- B.Planck's Law
- C.Wien's Displacement Law
- D.Newton's Law of Cooling
Model answer
What a good answer should say
- Wien's Displacement Law
Explanation
Why this works
Wien's Displacement Law states that the wavelength at which the emission of a black body spectrum is maximized is inversely proportional to the temperature of the black body, allowing us to determine temperature from peak wavelength.
