The maximum energy in the thermal radiation from a hot source occurs at a wavelength of \[11\times {{10}^{-5}}cm\]. 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 \[5.5\times {{10}^{-5}}cm\]. The value \[n\] is [CPMT 1991]
