About black body radiation, which one of the following is the WRONG statement?

Options

  1. AAll wavelengths are emitted by a black body
  2. BFor longer wavelengths, intensity is less.
  3. CFor shorter wavelengths, intensity is more.
  4. DFor all wavelengths, intensity is the same.

Correct answer

D. For all wavelengths, intensity is the same.

Step-by-step solution

Concept-based. A blackbody is an idealized emitter that has a continuous emission spectrum and a variation of intensity w.r.t wavelength is observed.
