Question

The maximum energy in the thermal radiation from a hot source occurs at a wavelength of $11\times {10}^{-5}$cm. According to Wien's law, the temperature of the source (on Kelvin scale ) for which the wavelength at maximum energy is :

Answer 1

$\lambda T=b$

$⟹T=\frac{b}{\lambda }=\frac{0.2898cm-K}{11\times {10}^{-5}cm}$

$⟹T=2634.545K$
