===About Radiowaves===
: [[Radiowave]]s [[transmit]] the least [[energy]] of all the [[Electromagnetic Wave|electromagnetic wave]]s.
: [[Radiowave]]s are [[Transverse Wave|transverse waves]].
: [[Radiowave]]s can travel through a [[vacuum]] as well as through [[gas]]es in the [[Earth's Atmosphere|Earth's atmosphere]].
: The [[speed]] of [[radiowave]]s through a [[vacuum]] is 300,000,000[[m/s]].
As a [[wave]] [[radiowave]]s can be:
*[[Transmit|Transmitted]] - [[Radiowave]]s can pass through a [[medium]].
*[[Absorb (physics)|Absorbed]] - The [[energy]] [[Energy Transfer|transferred]] by [[radiowave]]s can be taken in by certain [[material]]s, particularly [[metal]]s.
*[[Reflection|Reflected]] - [[Radiowave]]s can bounce off an [[interface]] between two [[medium|media]]. This can be either [[Diffuse Reflection]] or [[Specular Reflection]].
*[[Refraction|Refracted]] - [[Radiowave]]s can change direction when they cross the [[interface]] between two [[medium|media]].
====Properties====
: [[Radiowave]]s can cause alternating currents in [[metal]]s.
