Question

The Wien's displacement law express relation between

• A. wavelength corresponding to maximum energy and temperature
• B. radiation energy and wavelength
• C. temperature and wavelength
• D. colour of light and temperature

Answer 1

Answer: (A)

wavelength corresponding to maximum energy and temperature

Answer 2

Wien's displacement law states that the product of absolute temperature and the
wavelength at which the emissive power is maximum is constant i.e. $\lambda _{max} \,T$ = constant
Therefore it expresses relation between wavelength corresponding to maximum energy
and temperature.
