Question

The maximum energy in the thermal radiation from a hot source occurs at a wavelength of $$11$$×$$10-5$$ cm and temperature $$T1$$. According to Wien's law, the temperature of the source (on$$ Kelvin $$scale) $$nT1$$ for which the wavelength at maximum energy is $$5.5$$×$$10-5$$ cm. The value of n is:

Infinity Learn · Accepted Answer

According to Wein's law    λmT $$=$$ constantor $$($$λ$$m)1T1$$ $$=$$ $$($$λ$$m)2T2$$     $$11$$×$$10-5$$×$$T1$$ $$=$$ (5.5$$×$$10-5)×$$T2$$      $$T1$$ $$=$$ $$12T2n=2$$
