A black body at 1500K emits maximum energy of wavlength 20000`Å`. If sun emits maximum energy of wavelength `5500Å`, what would be the temperature of sun.

Explanation

To solve the problem, we will use Wien's Displacement Law, which relates the temperature of a black body to the wavelength at which it emits maximum energy. The law states:

\[ \lambda_{\text{max}} \cdot T = b \]

where:
- \(\lambda_{\text{max}}\) is the wavelength corresponding to maximum energy,
