Stars and other galactic objects may be moving towards or away from us at very h

Question

Stars and other galactic objects may be moving towards or away from us at very high speeds. This leads to a doppler shift of the electromagnetic radiation observed from this object. In each of the following cases, you are given the type of emitted radiation (as if you were at rest relative to the object) and the type of radiation towards which the observed light is shifted. From this information determine whether the object is traveling towards or away from you.
Radio waves emitted by the object is shifted towards infrared light.
Green light emitted by the object is shifted towards blue light.
Infrared radiation emitted by the object is shifted towards radio waves.
Infrared radiation emitted by the object is shifted towards red light.

Explanation / Answer

Radio waves emitted by the object is shifted towards infrared light :- towards

Green light emitted by the object is shifted towards red light :- away

Infrared radiation emitted by the object is shifted towards radio waves :- towards

Infrared radiation emitted by the object is shifted towards red light :- away
