==Key Stage 4==
===Meaning===
'''Microwaves''' are the second lowest [[frequency]] and second longest [[wavelength]] [[Electromagnetic Wave|electromagnetic waves]].
===About Microwaves===
====Properties====
: [[Microwave]]s can cause alternating currents in [[metal]]s.
: [[Microwave]]s can cause [[water]] [[molecule]]s to [[oscillate]], [[heating]] the [[water]].
====Applications====
: [[Microwave]]s can be used in communication because they can be created by [[Alternating Current|alternating current]] and can cause an [[Alternating Current|alternating current]] in [[metal]]s.
: [[Microwave]]s can be used for cooking because they cause [[water]] [[molecule]]s and [[fat]] [[molecule]]s to [[oscillate]] increasing the [[temperature]] of the [[food]].
====Dangers====
: [[Microwave]]s can cause internal heating of living creatures because they are made of [[water]] which is heated by [[microwave]]s.
