Presentation Transcript

  1. Production Of Electromagnetic Waves

  2. -the electric and magnetic fields at any point are perpendicular to each other and to direction of motion; • fields alternate in direction from point to point; • the electric and magnetic fields are “in phase”.

  3. EM waves are produced by accelerating electric charges.

  4. Speed of EM Waves

  5. Electromagnetic Spectrum

  6. Example • Calculate the wavelength: • Of a 60-Hz EM wave; • Of a 93.3 MHz FM radio wave; • Of a beam of visible red light from a laser at frequency 4.74x1014 Hz.
