We have to determine which of the given four principles can explain the difference in colors of the three shown stars.
To solve this problem, we will look at each given principle one by one and see if it is relevant.
The uncertainty principle
Heisenberg’s uncertainty principle states that the position and momentum of an electron cannot be determined accurately at the same time.
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?
