Waves

Waves

1. Mechanical

   • Mechanical waves move through a medium or a substance.
     • There is 3 structures.
       • Longitudinal wave: It produces compresion when traveling through a medium and pressure wave
       • Transverse wave: Particles of the medium move prenpendicular to the waves direction of travel characterized by peaks and valleys.
       • Surface waves: Particles of the medium vibrate both up and down and back and forth end up in a circle

2. electromagnetic

   • They are light waves.
     • Their are many variables in electromagnetic waves.
       • Visable Light waves: Next shortest wavelength and you can see it.
       • Ultra violet: Next shortest wavelength, you can see it and it can cause skin cancer.
   • They are compone of wavelength, longest, to shortest radio
   • • Microwaves: Short-wavelength and greater frequency and energy than radio waves.
     • Infrared Wave: They are used in night vision camara.
     • Visible light wave: You can see this light
     • Ultraviolet waves: This is sawn in the sun as well that can cause skin cancer.

3. Their difference is that electromagnetic waves travel in a vacuum and mechanical don't.

   • Mechanical waves are caused by amplitude and electromagnetic by the vibration of the charged particles.
   • Diffrences
