Question

“One of the most important scientific advances of the last 150 years is the discovery and application of ________________”

Fact OneA charged particle (either + or -) creates an electric field around it.

Fact TwoA moving charged particle (e.g. electric current) creates a magnetic field around it.

Fact ThreeA changing magnetic field can cause charged particles to move.

Electromagnetic WavesElectromagnetic waves are made up of oscillating electric and magnetic fields.All electromagnetic waves travel at the speed of light, c, in a vacuum.

c = speed of light = 3.0 x 108 ms-1

Electromagnetic waves do not require medium.
