Physics Question on Wave optics
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
A
the maximum of uT(λ) shifts to λmax/2
B
the maximum of uT(λ) shifts to 2λmax
C
the area under the curve becomes 16 times the original area
D
the area under the curve becomes 8 times the original area
Answer
the maximum of uT(λ) shifts to λmax/2
Explanation
Solution
The correct option is (A) : the maximum of uT(λ) shifts to λmax/2 and (B) : the maximum of uT(λ) shifts to 2λmax.
