Vedclass · Answer

(A) black body is an ideal body that absorbs and emits all incident electromagnetic radiation. According to Planck's Law of black body radiation,the intensity of radiation emitted by a black body depends on the wavelength and temperature. $1$. The intensity is not the same for all wavelengths; it follows a specific distribution curve (Planck's curve) that peaks at a particular wavelength depending on the temperature. $2$. Therefore,the statement 'For all wavelengths,intensity is same' is incorrect. $3$. As temperature increases,the peak intensity shifts towards shorter wavelengths,but the intensity varies continuously across the spectrum.
