==Key Stage 5==
===Meaning===
'''Annihilation''' is the process in which [[matter]] and [[antimatter]] interact converting all their [[Rest Mass|rest mass]] into [[energy]] resulting in a pair of [[Gamma Ray|gamma ray]] [[photon]]s being emitted in opposite directions.
===About Annihilation===
: '''Annihilation''' occurs when [[particle]]s of [[matter]] and [[antimatter]] interact at extremely close range.
: During '''annihilation''' the total [[Rest Mass|rest mass]] of, as well as their [[Kinetic Energy|kinetic energy]] results in the production of two [[Gamma Ray|gamma ray]] [[photon]]s.
: In '''annihilation''' [[Conservation of Momentum|conservation of momentum]] is conserved due to the [[momentum]] of the two [[Gamma Ray|gamma ray]] [[photon]]s travelling in opposite directions.
===Equation===
<math>2E_0 = 2hf</math>
Where
<math>E_0</math> = Rest Mass Energy of each particle.
<math>hf</math> = The [[energy]] of one [[Gamma Ray|gamma ray]] [[photon]] emitted.
<math>h</math> = [[Planck's Constant]]
<math>f</math> = The [[frequency]] of the emitted [[photon]]
