Question

mark out the correct statement with respect to thermal radiations emitted by black body​

Answer 1

Explanation:

wrong . it is not respected to thermal radiation emitted by blackbody

Answer 2

Question: Mark out the correct statement with respect to thermal radiations emitted by black body​:

1. At a given temperature, energy is distributed non uniformly among different wavelengths.
2. As temperature of the body is increased, energy content of all wavelengths decreases.
3. The product of spectral energy with spectral width for all equal Δλ is the same.
4. The thermal radiation emitted by a hot body is discrete spectra.

Answer: 1. At a given temperature, energy is distributed non uniformly among different wavelengths.

Black Body radiation

Black body emits radiation is different wavelengths. On arranging the wavelengths in increasing order we can get the black body spectrum.

As the wavelength increases the energy also increases until a particular maximum height then it starts decreasing.

Therefore the correct option is at a given temperature, energy is distributed non uniformly among different wavelengths.
