The maximum energy in the thermal radiation from a hot source occurs at a wavelength of $11\times 10^{-5}\text{cm}$. According to Wein'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 $5.5\times 10^{-5}\text{cm}$. The value $n$ is
