Q2: Wien's displacement law is ______?

وین کی نقل مکانی کا قانون ______ ہے؟

A. ν𝜆𝑚 = constant
B. None of these
C. 𝜆𝑚𝑇= constant
D. 𝜈𝑚𝑇= constant

Explanation

Wien's Displacement Law states that the product of the wavelength at which a blackbody emits maximum intensity ( $lambda_m$ ) and its absolute temperature ( $T$ ) is constant:
$lambda_m T = text{constant}$ .

It explains the inverse relationship between temperature and peak wavelength.

It meaning hotter objects emit radiation at shorter wavelengths.
