Electromagnetic Waves

Introduction

Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays.Magnetic waves are all around us and that is quite exciting.

  1.  James Clerk Maxwell 
  2. The study of electromagnetism deals with how electrically charged particles interact with each other and with magnetic fields.
  3. Four
  4. When an atomic particle, such as an electron, is accelerated by an electric field, causing it to move.
  5.  Seven
  6.  When an electric field couples with a magnetic field.
  7. No
    • The force of attraction or repulsion between electric charges is inversely proportional to the square of the distance between them.
    • Magnetic poles come in pairs that attract and repel each other, much as electric charges do.
    • An electric current in a wire produces a magnetic field whose direction depends on the direction of the current.
    • A moving electric field produces a magnetic field, and vice versa.
  9. Perpendicular to each other and to the direction of the wave.
  10. A wavelength is the distance between two consecutive peaks of a wave.
