The equation of the electric field of an electromagnetic wave propagating through free space is given by:
\( E = \sqrt{377} \sin(6.27 \times 10^{3} t - 2.09 \times 10^{-5} x) \, \text{N}/\text{C} \)
The average power of the electromagnetic wave is \( \left(\frac{1}{\alpha}\right) \, \text{W}/\text{m}^{2} \). The value of \( \alpha \) is ______.
[Take \( \sqrt{\frac{\mu_{0}}{\varepsilon_{0}}} = 377 \) in SI units]
