Estimate the surface temperature of sun. Given for solar radiations, `lambda_(m)=4753Å`. (`b=2.89xx10^(-3)` meter Kelvin)

Explanation

To estimate the surface temperature of the Sun using Wien's Displacement Law, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Wien's Displacement Law**:
Wien's Displacement Law states that the wavelength of maximum intensity of radiation emitted by a black body is inversely proportional to its temperature. The formula is given by:
\[
\lambda_m \cdot T = b
