Many galaxies have supermassive black holes at their centers. As material swirls around such a black hole, it is heated, becomes ionized, and generates strong magnetic fields. The resulting magnetic forces steer some of the material into high-speed jets that blast out of the galaxy and into intergalactic space. The light we observe from the jet has a frequency of 6.66x10^14 Hz (in the far ultraviolet region of the electromagnetic spectrum), but in the reference frame of the jet material, the light has a frequency of 5.55x10^13 Hz (in the infrared). What is the speed of the jet material with respect to us?
A person on earth communicating via radio transmission with an astronaut on the moon asks a question. At the time of transmission the moon is 4.00 x 10^5 km from earth, and the speed of radio waves if 3.00 x 10^8 m/s. How long must the person on earth wait for a response if the astronaut answers 2.50 s after the message is received?
Light is emitted by a distant star at a frequency of 4.56 x 10^24 Hz. a) If the star is moving toward Earth at a speed of 2750 km/s, what frequency light will be detected by observers on Earth? b) Is this considered a Blue shift or a Red shift?
