Physical Sciences Thermodynamic and Statistical Physics Blackbody Radiation and Planck's Distribution Law
Consider the intensity I(T) vs. frequency ν graph of a black body, where the temperature T of the black body is initially T0 . If the temperature is increased to 4T0 , which of the following statements are true?
1
The frequency corresponding to the maximum intensity shifts to \( 4\nu_{\text{max}} \).
2
The intensity at the maximum point becomes 16 times the original intensity.
3
The total energy emitted per unit area under the curve increases by a factor of 256.
4
The maximum wavelength of the emitted radiation becomes \(\lambda_{\text{max}}/4\) .
