Two coherent sources of light interfere. The intensity ratio of two sources is $\displaystyle 1: 4$. For this interference pattern if the value of $\displaystyle \frac{\mathrm{I}_{\text {max }}+\mathrm{I}_{\text {min }}}{\mathrm{I}_{\text {max }}-\mathrm{I}_{\text {min }}}$ is equal to $\displaystyle \frac{2 \alpha+1}{\beta+3}$, then $\displaystyle \frac{\alpha}{\beta}$ will be :
