==Key Stage 4==
===Meaning===
'''Radiowaves''' are the lowest [[frequency]] and longest [[wavelength]] [[Electromagnetic Wave|electromagnetic waves]].
===About Radiowaves===
: [[Radiowave]]s [[transmit]] the least [[energy]] of all the [[Electromagnetic Wave|electromagnetic wave]]s.
====Properties====
: [[Radiowave]]s can cause alternating currents in [[metal]]s.
: [[Radiowave]]s can pass through many non-metals unaffected.
====Applications====
: [[Radiowave]]s can be used in communication including radio broadcasts and television broadcasts because they can be created by [[Alternating Current|alternating current]] and can cause an [[Alternating Current|alternating current]] in [[metal]]s.
====Dangers====
: There are no dangers of [[radiowave]]s.
