Waves

Waves

1. mechanical

   • created due to variations between electric and magnetic field
     • are light waves
       • come in all forms
         • propagate energy forward they dont use a medium
           • A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum.
   • These waves travel more quickly through higher-density media.
     • These waves need a medium (solid, liquid, or gas) to propagate.
       • Examples of mechanical waves are:
         • Seismic waves, water waves and sound waves

2. electromagnetical

   • transfers energy to medium
     • all types of sounds
   • structure and function
     • don't need a medium to propagate
       • These waves can move through a vacuum and can also move through mediums
         • Some examples of electromagnetic waves are:
           • Radio waves, Microwaves, Infrared waves, Visible light waves, Ultraviolet waves, X-ray waves and Gamma ray waves
           • All electromagnetic waves are examples of radiation
             • Radiation is the transmission of energy in the form of waves through space or through a medium.
