Electromagnetic Waves
Physics: IB Diploma Higher Level, topic 3.2.3
Electromagnetic Waves
All electromagnetic waves are transverse and travel at the same speed.
Transverse
- All electromagnetic waves are transverse waves.
- The electric and magnetic fields oscillate perpendicular to the direction of energy propagation.
- All electromagnetic waves travel at the speed of light, c, in a vacuum.
- The speed of light is c = 3 x 108 m/s.
