In spectral radiancy curve for cavity radiation, the wave-length of th...


Explanation:

Wien's Displacement Law:
- According to Wien's Displacement Law, the wavelength of the maximum spectral radiancy of cavity radiation is inversely proportional to the temperature of the radiating body.
- Mathematically, λ_max ∝ 1/T, where λ_max is the wavelength of maximum spectral radiancy and T is the temperature.

Relationship with Temperature:
- As the temperature of the radiating body increases, the wavelength of the maximum spectral radiancy decreases.
- This means that at higher temperatures, the peak of the spectral radiancy curve shifts towards shorter wavelengths (higher frequencies).
- Conversely, at lower temperatures, the peak of the curve shifts towards longer wavelengths (lower frequencies).

Significance:
- This relationship is important in understanding the behavior of blackbody radiation and helps in determining the temperature of a radiating body based on its spectral radiancy curve.
- The shift in the peak wavelength with temperature is a fundamental aspect of thermal radiation and has implications in various fields such as astronomy, physics, and engineering.

Therefore, the correct answer is option 'B' - the wavelength of the maximum spectral radiancy decreases with increasing temperature, as per Wien's Displacement Law.
