Statement I: As the temperature of the black body increases, the wavelength at which the spectral intensity `(E_lamda)` is maximum decreases.
Statement II: The wavelength at which the spectral intensity will be maximum for a black body is proportional to the fourth power of its absolute temperature.

Options

A. Statement I is true, Statement II is true and Statement II is the correct explanation for statement I.
B. Statement I is true, statement II is true and statement II NOT the correct explanation for Statement I
C. Statement I is true, Statement II is false.
D. Statement I is false, statement II is true.

Answer

C

Explanation

From Wien's law `lamda_mT=`constant i.e., peak emission wavelength `lamda_mprop(1)/(T)`. Hence at T increases `lamda_m` decreses.
