Problem
Stars do not all have the same temperature. The color of light emitted by stars is characteristic of the light emitted by hot objects. Telescopic photos of three stars are shown below:
(i) the Sun, which is classified as a yellow star, (ii) Rigel, in the constellation Orion, which is classified as a blue-white star, and (iii) Betelgeuse, also in Orion, which is classified as a red star.
Which of the following principles is relevant to your choice of answer for Part A: The uncertainty principle, the photoelectric effect, blackbody radiation, or line spectra?
