The broadening of spectral lines can be caused by:
A)density of the hot medium.
B)thermal motion of the hot atoms.
C)rotation of the star.
D)magnetic fields of the star.
E)all of the above.

Question

Quizplus · Accepted Answer

The broadening of spectral lines can be caused by various factors such as the density of the hot medium, thermal motion of the hot atoms, rotation of the star, and magnetic fields of the star. Therefore, all of the above choices contribute to the broadening of spectral lines. The broadening of spectral lines can be caused by all of the given options. The density of the hot medium can affect the broadening of spectral lines through collisional broadening. Thermal motion of the hot atoms can cause Doppler broadening. Rotation of the star can cause rotational broadening. Finally, magnetic fields of the star can cause magnetic broadening.
