'''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==
CElectromagnetic 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>

EYield electromagnetic w[[Wave equation]]
: <math>\nabla^2 E = - \omega E</math>
: <math>\nabla^2 B = - \omega B</math>⏎
⏎
Solve 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>
