B) temperature
C) radial velocity
D) no radiation

Question

Quizplus · Accepted Answer

The Doppler shift is a change in frequency or wavelength of waves as the source and observer move relative to each other. In astronomy, this is often used to measure the radial velocity of an object, meaning how fast it is moving towards or away from us. This information can then be used to determine other properties of the object, such as its distance, mass, or orbital parameters. The Doppler shift cannot directly determine energy or temperature, and the option for "no radiation" is not applicable in this context.
