Question

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

• A. 2
• B. 4
• C.
• D. 1

Answer 1

The correct option is C

$\therefore T=\frac{b}{{\lambda }_m}$
