The maximum energy is the thermal radiation from a hot source occurs at a wavelength of `11 xx 10^(-5) cm`. According to Wien’s law, the temperature of this 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 xx 10^(-5) cm`. The value of `n` is:
A. 2
B. 4
C. `(1)/(2)`
D. 1
