The Electromagnetic Spectrum Electromagnetic waves are signals that oscillate; i.e., the amplitudes of the electric and magnetic fields vary at a specific crate. The field intensities fluctuate up and down, and the polarity reverses a given number of times per second. The electromagnetic waves very sinusoidally. Their frequency is measured in cycles per second (cps) … Read more
