To find the surface temperature of the sun using Wien's law, we follow these steps: ### Step 1: Understand Wien's Law Wien's law states that the wavelength at which the intensity of radiation is maximum (\( \lambda_{m} \)) is inversely proportional to the absolute temperature (T) of the black body. Mathematically, it is given by: \[ \lambda_{m} \cdot T = b \] where \( b \) is Wien's constant. ...
