Which law relates the wavelength of peak emission to the temperature of a body?
AWien's deployment law
BWien's deportment law
CWien's displacement law
DWien's development law
Answer & Solution
Correct answer: C. Wien's displacement law
1. A hot body radiates across a range of wavelengths.
2. The wavelength that carries the most energy shifts as the body gets hotter.
3. The relation between that wavelength and temperature is Wien's displacement law.
4. The value of the constant is 2.9 times ten to the minus three metre kelvin.
