What are the three main characteristics that you notice in the emission spectra as the temperature of the blackbody radiators (stars) increases?

Answer 1

The three main characteristics that you notice in the emission spectra as the temperature of the blackbody radiators (stars) increases are as follows-

1) Wien’s Displacement Law, which states that the frequency of the peak of the emission (f_max) increases linearly with absolute temperature (T). Conversely, as the temperature of the body increases, the wavelength at the emission peak decreases.

2) From stefan-boltzman law which relates the total energy to the temperature of the black body i.e ET⁴. So the total energy increases as the temperature increases.

3) The intensity (or flux) at all wavelengths increases as the temperature of the blackbody increases.
