About black body radiation, which one of the following is the WRONG statement?
  1. All wavelengths are emitted by a black body
  2. For longer wavelengths, intensity is less.
  3. For shorter wavelengths, intensity is more.
  4. For all wavelengths, intensity is the same.

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.
