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.
