'''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==
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>

Solve those equation above yield Electromagnetic wave equation andElectromagnetic wave equation
: <math>\nabla^2 E = - \omega E</math>
: <math>\nabla^2 B = - \omega b</math>
: <math>\omega = \sqrt{\frc{1}{T}}</math>
: <math>T = \mu \epsilon</math>
