WAVES

WAVES

1. Electromagnetic

   • Light waves
   • Comes in all forms depending on how is it spread.
   • It does not need a medium.
   • A static charge creates an electric field and a moving charge creates a magnetic field.
     • radio waves have the least energy which is associated with frequency.
       • Infrared waves are commonly used in devices like remote controls to transmit a signal in the IR range.
   • The types of electromagnetic waves from longest wavelength to shortest are Radio, Infrared (IR), Visible Light, Ultraviolet (UV), X-Ray, and Gamma Ray waves.
   • Microwave uses energy in microwaves to vibrate food molecules, heating them up.
   • Your eyes are organs that detect only a frequency in the visible light spectrum of the electromagnetic waves.
   • With more energy, these waves become a bit more dangerous as they can penetrate further through ultra violet including our skin.
   • X-rays have additional penetrating power and are more dangerous.
   • Gamma rays have the shortest wavelength and highest frequency and highest energy of all electromagnetic waves.

2. Magnetic

   • Types od sound
   • move through medium/substance
   • SOLID/LIQUID/GAS
   • Need to have particles to transfer energy
