Consider two identical bodies, one at 5000 K and the other at 2000 K. With the aid of a suitable diagram, explain: (a)Which of the two bodies will emit more radiation in the shorter-wavelength region. (b)Which of the two bodies will emit more radiation at a wavelength of 20 μm

Does the height of the baselines measured correspond with losses simply arising from reflection (i.e. 0.036)? If not, what other sources of wavelength-independent losses could there be?Explain

Does the height of the baselines measured correspond with losses simply arising from reflection (i.e. 0.036)? If not, what other sources of wavelength-independent losses could there be? (Note that colorant ions usually result in absorption peaks).
