The value of Wien's constant is:

Correct answer: A. 2.90 x 10^-3 mK

  • A. 2.90 x 10^-3 mK
  • B. 3.34 x 10^-4 mK
  • C. 4.22 x 10^-7 mK
  • D. 3.42 x 10^-8 mK

Explanation

Wien's Law states that the product of the wavelength corresponding to the maximum intensity of radiation and the temperature of the body in Kelvin is a constant, known as Wien's constant. The correct value of this constant is approximately 2.897 x 10-3 mK. This relationship helps determine the peak wavelength of radiation emitted by a blackbody at any given temperature. Option A correctly reflects this value. The other options are incorrect as they suggest values that are either too small or not relevant to Wien's constant.

About Quantum Theory and Radiation

Quantum theory treats electromagnetic radiation as packets of energy called photons, with energy proportional to frequency through E equals hf. The topic covers Planck's hypothesis, photon momentum, the photoelectric effect, threshold frequency, work function and wave particle duality, distinguishing quantised energy exchange from classical continuous radiation.
