Question

The maximum energy in the thermal radiation from a hot source occurs at a wavelength of 11 ×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 × 10⁻⁵ cm. The value n is(a) 2(b) 4(c) 1/2(d) 1

Answer 1

The right answer is option d
