Heat carried by electromagnetic waves (IMAGE) National Institutes of Natural Sciences Caption Heat is carried by electromagnetic waves, which simultaneously slow down the high-speed particle beam (red line) and heat up the plasma particles (green line). Distortion of the velocity distribution is observed due to the acceleration of the particles as a result of the electromagnetic waves.
