Secondary waves cannot travel through How are primary waves and secondary waves different? What type of wave does sound travel in? What is transferred by electromagnetic waves? What kind of waves, by definition, must have a physical medium through which to travel?

Radio waves, on the other hand, are fundamentally different from sound waves. They are electromagnetic. They result from oscillations of the electromagnetic field and don't need a physical medium, so they, like other types of electromagnetic wave, can travel basically anywhere, through a vacuum,...
MALE PROFESSOR: So are there are any questions before we continue our discussion of different types of electromagnetic waves?Um, today we'll focus on radio waves, and specifically, very low frequency radio waves.Ah Yes, Tim? MALE STUDENT: Are you going to talk at all about the difference ...
Radio frequency (RF, rf) measures electromagnetic radio waves, and using antennas and transmitters, it can be used for wireless broadcasting and communications.
What are waves produced by?Waves:A wave is a moving vibration. A vibration is anything that moves back and forth, up and down, etc. It can result from the vibration of a material (such as your vocal chords or a pendulum) or electric and magnetic fields (or the vibration of energy)....
