The maximum energy in the thermal radiation from a hot source occurs at a wavelength of $11 \times 10^{-5}\, cm$ . According to Wien's law, the temperature of the source (on kelvin scale) will be $n$ times the temperature of another source (on Kelvin scale) for which the wavelength at maximum energy is $5.5 \times 10^{-5}\, cm$ . The value of $n$ is
