Question

Transcribed Image Text:Why does the Doppler effect lead to a shift in the wavelength of the light emitted by a star, but to a broadening of emitted light in a gas?
Check all that apply.
The wavelength of a star is shifted because all the photon emitters are moving in the same direction with respect to the observer.
✓ The wavelength of a star is shifted because all the photon emitters are moving randomly and with equal probability in all directions with respect to the observer.
✓ Emitted light in a gas is broadened because the atoms move randomly and with equal probability in all directions with respect to the observer.
Emitted light in a gas is broadened because the atoms move in opposite directions with respect to the observer.
