Wien's Law Temperature Ratio
The maximum energy in the thermal radiation from a hot source occurs at a wave length of 11 × 10⁻⁵ cm, According to Wien's law, the temperature of the sources (on Kelvin scale) will be n times the temperature of another source (on kelvin scale) for which the wave length at maximum energy is 5.5 × 10⁻⁵ cm. The value of n is
