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.

<p>All the statements (A, B, C, D) provided about black bodies are correct. </p> <p>(A) A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. It also emits energy in the form of electromagnetic radiation.</p> <p>(B) The frequency distribution of the emitted radiation by a black body indeed depends on its temperature. This phenomenon is described by Planck&#39;s law.</p> <p>(C) The intensity vs frequency curve for a black body, also known as the Planck&#39;s curve, does indeed pass through a maximum value for a given temperature.</p> <p>(D) The frequency at which the maximum intensity occurs increases with the temperature of the black body. This is stated in Wien&#39;s displacement law.</p> <p>So, the number of incorrect statements about the black body from the above is 0.</p>
