Question:
The spectral energy density uT(λ) vs wavelength (λ) curve of a black body shows a peak at λ = λmax. If the temperature of the black body is doubled, then
The spectral energy density uT(λ) vs wavelength (λ) curve of a black body shows a peak at λ = λmax. If the temperature of the black body is doubled, then
Updated On: Oct 1, 2024
- the maximum of uT(λ) shifts to λmax/2
- the maximum of uT(λ) shifts to 2λmax
- the area under the curve becomes 16 times the original area
- the area under the curve becomes 8 times the original area
