Electromagnetic is the huge term, it covers something from approximately a hundred KHz to 3 hundred GHz Microwave is extra particular to a particular phase of the spectrum It covers from 1000 MHz to 3 hundred GHz Microwave ovens are working at 2450 MHz (2.40 5 GHz) cellular telephones 1900 MHz satellite tv for pc television, the sign interior the cable from the antenna to the receiver is 950 to 1450 MHz The sign gained from the satellite tv for pc 11 GHz to twelve GHz (relies upon on provider provider) wish this appropriate solutions your question Guru

EM radiation in a vacuum always travels at the speed of light, relative to the observer, regardless of the observer's velocity

The first answer is correct. I don't know why someone would call it a bad answer. The speed can be affected by matter or gravity but your question is specifically about in a vacuum, no intervening matter.
