The radiation emitted by the surface of the Sun emits maximum power at a wavelength of about $500$ $\mathrm{n}\mathrm{m}$. Assuming the Sun to be a blackbody emitter. If its surface temperature $\left(\mathrm{K}\right)$ is given by $\mathrm{\alpha }\bullet \mathrm{\beta }\times {10}^{\mathrm{\gamma }}$ then fill the value of $\left(\mathrm{\alpha }+\mathrm{\beta }+\mathrm{\gamma }\right)$. (Wien’s constant is given by $2.898$ $\mathrm{m}\mathrm{m }\mathrm{K}$ )
