Waves

1. Mechanical

   • Considered a periodic disturbance
   • It is all types of sound including music and speaking
   • Moves through a medium to travel
   • Moves through the air
   • Doesn't have to be a liquid or gas
   • Electromagnetic radiation travels in waves frequency
   • If the wavelengths shorten then the frequencies increase.

2. Electromagnetical

   • Waves no medium to travel
   • They are light waves
   • Light waves don't need a medium, that's why we can see light
   • There's a variety of electromagnetical waves like heaters, lamps, etc.
   • Structure
     • Electromagnetic waves are created by the vibrating charged particles.
     • Static charge: creates an electric field moving charge: magneticfield
     • The more energy contained in the wave the more penetrating power.
