Question

Which of the following is correct relation between ${\lambda }_m$ (wavelength corresponding to maximum energy of emission) and T (absolute temperature)?

• A. ${\lambda }_m/T$ = constant
• B. ${\lambda }_{m}T$ = constant
• C. ${\lambda }_m^2/T$ = constant
• D. ${\lambda }_m/T^4$ = constant

Answer 1

Answer: (B)

${\lambda }_{m}T$ = constant

${\lambda }_m\times T=constant$. This is Wien's displacement law
option (B) is the correct answer.
