Created page with "==Key Stage 4== ===Meaning=== '''Infrared''' are the third lowest frequency and third longest wavelength electromagnetic waves. ===About Infr..."

New page

==Key Stage 4==
===Meaning===
'''Infrared''' are the third lowest [[frequency]] and third longest [[wavelength]] [[Electromagnetic Wave|electromagnetic waves]].

===About Infra-red===
====Properties====
: [[Infra-red]] can cause [[atom]]s and [[molecule]]s to [[vibrate]], [[heating]] a [[material]].
====Applications====
: Different [[frequency|frequencies]] of [[infra-red]] have different [[application]]s.
: [[Infra-red]] is used in remote controls and night vision because it is invisible to the [[human]] [[eye]] but can be [[transmit]]ed through the [[air]] without being [[Absorb (Physics)|absorbed]].
: [[Infra-red]] can be used in [[Thermal Imaging|thermal imaging]] because [[object]]s emit [[infra-red]] [[radiation]] due to their [[temperature]]. The higher the [[temperature]] the more [[infra-red]] they [[emit]].
: [[Infra-red]] can be used to cook food because it can cause [[atom]]s and [[molecule]]s to [[vibrate]], [[heating]] the food.
====Dangers====
: [[Infra-red]] can cause skin burns because it can cause [[atom]]s and [[molecule]]s to [[vibrate]], [[heating]] the [[material]].
