Elektromagnetik radiashion
For fysiks, elektromagnetik radiashion (EMR) konsist of waves of di elektromagnetik (EM) field, wey dé propagate thru space and karry momentum and electromagnetic radiant enerjy.[1] Types of EMR inklud radio waves, maikrowaves, infrared, (visibul) laight, ultravaiolet, X-rays, and gamma rays, all of which bi part of di elektromagnetik spektrum.
