Physical Science Notes

2 Electromagnetic Waves
Electromagnetic waves are made by vibrating electric charges and don't require a medium to travel through. The energy carried by an electromagnetic wave is radiant energy.

3

4 Speed of Light The "speed of light" is the speed of all electromagnetic waves in a vacuum of space which is 300,000 km/s. this is nature's speed limit - a medium will only slow down the wave. Electromagnetic waves usually travel slowest in solids and liquids and fastest in gases.
