Study Notes
Electromagnetic Waves
- An accelerating charge produces a changing magnetic field according to the wave model.
- The delay in the predicted occurrence of Io's eclipse is caused by the finite speed of light, recognized by Christian Huygens.
- Electromagnetic radiation (EMR) moves away from the source of the accelerating charge at the speed of light.
- Christian Huygens used Ole Rømer's method of observing the eclipses of Io to measure the speed of EMR.
- Changing electric and magnetic fields that travel as waves are called electromagnetic waves.
- The reason they are called electromagnetic waves is because they consist of electric and magnetic fields that oscillate at right angles to each other and to the direction of propagation.
