The number of incorrect statement/s about the black body from the following is ________ (A) Emit or absorb energy in the form of electromagnetic radiation. (B) Frequency distribution of the emitted radiation depends on temperature. (C) At a given temperature, intensity vs frequency curve passes through a maximum value. (D) The maximum of the intensity vs frequency curve is at a higher frequency at higher temperature compared to that at lower temperature.

1. 0
2. 1
3. 2
4. 3

Correct answer: 0

Solution

All the statements provided about black bodies are accurate. A black body is defined by its ability to emit and absorb all frequencies of electromagnetic radiation, and its emission characteristics, including intensity distribution and peak frequency, are indeed temperature-dependent.
