Waves

Waves

1. mechanical

   • don't travel as a vacuum
   • need a medium like water, air, anything to travel
   • caused by wave amplitude
   • sound
     • ocean waves
   • propagates through a medium doesnt need to be liquid or gas
   • like the vibration of the track of a train
   • longitudinal waves
     • transversal
       • surface waves

2. electromagnetical

   • travel in a vacuum
   • cause by the vibration of the charged particles
   • light waves in all forms
     • heating up something
       • texting someone
         • turning on lights
   • propagate energy forward without medium
   • microwave waves
     • shorter wavelenght
       • longer frecuency
     • visible light waves
     • ultraviolet waves
