Wien's displacement law казва, че:
https://en.wikipedia.org/wiki/Black-body_radiation#Wien's_displacement_law

" ... the wavelength at which the intensity per unit wavelength of the radiation produced by a black body is at a maximum, λ max , is a function only of the temperature:"

${\displaystyle \lambda _{\max }={\frac {b}{T}}}$

Тогава:

$T_2 = T_1/2$

${\displaystyle \lambda_1{\max }={\frac {b}{T_1}}}$

${\displaystyle \lambda_2{\max }={\frac {2b}{T_1}}}$

${\displaystyle \lambda_2{\max }=2 \lambda_1{\max }}$

Или отговор Б)
