Question

According to Wein's displacement law

• A. $\lambda T =$ constant
• B. $\lambda/T =$ constant
• C. $\lambda \propto (1/T)$
• D. both (b) and (c)

Answer 1

Answer: (A)

$\lambda T =$ constant

Answer 2

Wien?? displacement law states that the absolute temperature of a black body and the peak wavelength of its radiations are inversely proportional. i.e. $\lambda \propto 1/T$ or $\lambda =$ constant
