All forms of electromagnetic radiation, whether they're called waves or rays, are generated by particles in motion. In a radio signal, for example, negatively charged electrons quickly move back ...

They're your eyes, and they receive signals that ... yet they are all forms of electromagnetic radiation—waves moving through space (not just outer space) that have an electric and magnetic ...

Speaker one We’re going to investigate emissions of infrared radiation first and then absorption by completing two short experiments. We’re going to use a Leslie cube to investigate emissions.

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays, and infrared. All of these forms of electromagnetic ...

beyond the radiation belts. In contrast to radial diffusion, which necessarily acts over large distances of the order of 1 Re, gyro-resonant wave acceleration is the most effective form of ...

Remember to look at your lab book or your notes from the practical activities you have done when you're revising for the ... are measuring the image of the wave, rather than the wave itself.
