If Curves of Intensity Versus Wavelength Are Plotted for a Single

question 82

Multiple Choice

If curves of intensity versus wavelength are plotted for a single object at various temperatures, it is found that the curves never cross. Why is this important?

• A) If the curves do not cross, then the object is not a blackbody.
• B) The only situation in which the curves do not cross is when the source is a neutron star-essentially an atomic nucleus the size of a star.
• C) If the curves do not cross it means that monochromatic light has been emitted from the source.
• D) Because each curve is unique, in theory it is possible to determine the temperature from a single point on a blackbody curve.
