→About Electromagnetic Waves
: '''Electromagnetic waves''' are [[transverse]] because the [[oscillation]] of [[Electrostatic Field|electrostatic]] and [[Magnetic Field|magnetic]] [[Force Field|field]]s is [[perpendicular]] to the direction of [[Energy Transfer|energy transfer]].
: '''Electromagnetic waves''', like all [[wave]]s, carry [[energy]] and [[information]] but they do not [[transfer]] [[mass]] from one location to another.
: '''Electromagnetic waves''' can pass through any [[transparent]] [[medium]].
: '''Electromagnetic waves''' do not need [[matter]] to be [[transmit]]ted and can travel through a [[vacuum]].
: All '''electromagntic waves''' travel at 300,000,000m/s through a [[vacuum]].
: The [[property|properties]] of '''electromagntic waves''' depend on their [[frequency]] and [[wavelength]]. The lowest [[frequency]] [[transmit]]s the least [[energy]] so they are the least dangerous. The highest [[frequency]] [[transmit]]s the most [[energy]] so they are the most dangerous.
