About black body radiation, which one of the following is the WRONG statement?
- A All wavelengths are emitted by a black body
- B For longer wavelengths, intensity is less.
- C For shorter wavelengths, intensity is more.
- D For all wavelengths, intensity is the same.
Answer & Solution
Correct Answer
(D) For all wavelengths, intensity is the same.
Step-by-step Solution
Detailed explanation
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.
