- For a blackbody at given temperature, Amax is the wavelength at the peak of the radiation distribution. What happens to Amax as the temperature increases? (a) It increases. (b) It decreases. (c) It remains constant. (d) It depends on the size of the blackbody.An idealized radiating object does not reflect or scatter any radiation but instead absorbs all of electromagnetic energy that falls on it. can you explain why astronomers call such an object a blackbody? keep in mind that even stars, which shine brightly in a variety of colours, are considered blackbodies. Explain why?What is the wavelength of maximum intensity and the total energy emitted by a celestial object at 2.7 K above absolute zero? Which part of the EM spectrum does the wavelength of maximum intensity lie?
