Question

Many galaxies have supermassive black holes at their centres.As material swirls around such a black hole,it is heated,become ionized and generates strong magnetic fields.the resulting magnetic forces steer some of the material into high speeds jets that blast out of the galaxy and into intergalactic space.The light we observe from the jet in fig.has frequency of 6.66(10^14 hz)

(in the far ultra voilet region of the electromagnetic spectrum)but in the reference frame of the jet material the light has frequency of 5.55(10^13 hz)(in the infrared).What is the speed of the jet material with respect to us?
