• ​Electromagnetic waves are waves that can travel through an empty space or vacuum

• It is made up of electric and magnetic fields

• They are TRANSVERSE WAVES

​​Electromagnetic Waves

• They travel at right angles

• They have crests, troughs, amplitude, wavelength, frequency, and energy

• They do not require a medium to travel through

• ​Are made up of positive and negative charges

• They have different sources or properties

• S.I. Unit is Newton/Coulomb

• Measured by an electrometer

​​Electric Fields

• Are produced by electric charges

• They have North and South poles

• S.I. Unit is Tesla

• ​Measured by a magnometer

Magnetic Fields

• Radio Waves have the longest wavelength transmits ener
