When the temperature of a black body is lowered, the wavelength associated to the maximum intensity
Correct answer: C. shifts to the longer wavelength.
- A. becomes zero.
- B. remains the same.
- C. shifts to the longer wavelength.
- D. shifts to the shorter wavelength.
Explanation
When the temperature of a black body is lowered, according to Wien's displacement law, the wavelength associated with the maximum intensity shifts to a shorter wavelength. This is because as the temperature decreases, the peak of the black body radiation spectrum moves towards shorter wavelengths. The other options are incorrect because the wavelength does not become zero, remain the same, or shift to a longer wavelength when the temperature is lowered.

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.
