Electromagnetic wave common properties
- They are all transverse wave
- They travel at the same speed in vacuum; 3 X 108 m/s
- They can travel through all matter (solid, liquid, gas) and
vacuum; thus having the ability to transfer energy from one
place to another with or without a medium.
- They abide by the law of reflection and refraction
