Waves

Waves

1. Mechanical

   • Waves move through a medium
   • They cannot travel through a vacuum as space
   • Examples: Sound waves, Ocean waves, Earthquake waves.

2. Electromagnetical

   • A wave that can travel through the vacuum of space.
   • Example: Light waves, Radio waves, Microwaves, X-rays, Gamma rays and Ultraviolet rays.
   • Waves propagate energy but do not use a medium
   • If electromagnetic waves were magnetica waves, there would not be LIGHT or LIFE on EARTH!
