CBSE · Class 11 · Physics · Thermal Properties of MatterWhich of the following expressions correctly represents Wien's Displacement Law?
Step-by-Step Solution
Wien's Displacement Law states that the wavelength corresponding to maximum energy emission ($\lambda_m$) is inversely proportional to absolute temperature ($T$), i.e., $\lambda_m T = b$ (constant). Hence, option A is correct.
Detailed Options Breakdown
Option : $\lambda_m T = \text{constant}$ (Correct Answer)
Correct choice. Refer to the step-by-step verified solution guidelines above for details.
Option 1: $\frac{\lambda_m}{T} = \text{constant}$
