Wien's displacement law is ______?

وین کی نقل مکانی کا قانون ______ ہے؟

𝜆𝑚𝑇= constant

𝜈𝑚𝑇= constant

ν𝜆𝑚 = constant

None of these

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.
