'''Electromagnetic radiation''' comes in many different types, although the differences between them are quantitative rather than qualitative.  This teaching aid lists the different types that are generally recognised.

Electromagnetic radiation is an Electromagnetic oscillation wave that travels at speed of visible light carries[[Quantum]]'s energy called [[Photon]]

==Electromagnetic oscillation wave==
Electromagnetic oscillation can be describe by 4 Maxwell's vector equations
: <math>\nabla \cdot E = 0</math>
: <math>\nabla \times E = \frac{1}{T} E</math>
: <math>\nabla \cdot B = 0</math>
: <math>\nabla \times B = \frac{1}{T} B</math>

Yield electromagnetic [[Wave equation]]
: <math>\nabla^2 E = - \omega E</math>
: <math>\nabla^2 B = - \omega B</math>

Solve those equations above gives electromagnetic [[Wave function]]
: <math>E = A Sin \omega t</math>
: <math>B = A Sin \omega t</math>

Provided that
: <math>\omega = \sqrt{\frac{1}{T}}</math>
: <math>T = \mu \epsilon</math>

==Electromagnetic radiation ==
Electromagnetic radiation generates Photon of Quanta's energy in 2 states
* [[Radiant Photon]] at Threshold frequency ,fo  <math>f_o = \frac{C}{\lambda_o}</math>
* [[Electric Photon]] at frequency greater Threshold frequency 

These Photon of Quanta's energy cannot exist in 2 states at the same time that gives ris to Heinsberg [[Uncertainty Principle]] that can be describe mathematically
: <math>\Delta p \Delta \lambda > \frac{1}{2} \frac{h}{2 \pi} = \frac{h}{4 \pi}</math>
