The electromagntic waves you should know in order from lowest frequency (longest wavelength) to highest frequency (shortest wavelength) are:Įlectromagnetic waves, are transverse with the vibration at right angles to the motion of the wave. The highest frequency transmits the most energy so they are the most dangerous. The lowest frequency transmits the least energy so they are the least dangerous. The properties of electromagntic waves depend on their frequency and wavelength. All electromagntic waves travel at 300,000,000m/s through a vacuum. Electromagnetic waves do not need matter to be transmitted and can travel through a vacuum.
Electromagnetic waves can pass through any transparent medium. Electromagnetic waves, like all waves, carry energy and information but they do not transfer mass from one location to another. An electromagnetic wave is a transverse wave which travels through a vacuum at 300,000,000m/s.Īn electromagnetic wave is a transverse wave which transfers energy by oscillating electrostatic and magnetic fields.Ībout Electromagnetic Waves Electromagnetic waves are transverse because the oscillation of electrostatic and magnetic fields is perpendicular to the direction of energy transfer.
