Question

Calculate the energy density per unit wavelength in a black body cavity at a
temperature 2000 K at a wavelength of 4000 Å.
*​

Answer 1

Answer:

Applying Wien's displacement law, λ T = constantwhere, λ = wavelength of maximum energy, T = absolute temperatureLet λ1 be required wavelength at 1000K ..

Answer 2

Answer:

Applying Wien's displacement rule, 1 is the necessary wavelength at 1000K, T = absolute temperature, = wavelength of maximum energy, and = constant.

Explanation:

In 1893, Wilhelm Wien developed Wien's law, also known as Wien's displacement law, which asserts that different wavelengths of black body radiation have temperature peaks that are inversely proportional to temperatures. The law is expressed mathematically as m an x = b T.

According to Wien's displacement law, the black body radiation curve has a peak at a wavelength that is inversely proportional to temperature for different temperatures. The wavelength with the highest intensity is the characteristic wavelength that is specified.

⇒λ=constant\s⇒λ×2000Κ=λ

′ \s ×3000K \s⟹λ \s′ \s = \s3 \s2 \s​ \s λ
