Waves

Waves

1. A static charge creates electric field and a moving charge created a magnetic field

   • Electric and magnetic fields in an electromagnetic wave vibrate perpendicular (90 d) to each other

2. Range of Electromagnetic Waves

   • Electromagnetic waves form longest wavelength to shortest
     • Radio waves
       • Infrared (IR)
         • Visible Light
           • Ultraviolet
             • X-Ray
               • Gamma Ray
                 • Higher frequency contains more energy, so gamma rays have more energy, and radio waves the least
                   • Frequency describes how many waves per second a wavelength produces
       • Microwave
     • Electromagnetic spectrum
       • Refers to many types of radiation released from stars that travel in waves
