===Meaning===
'''Electromagnetic waves''' are [[Transverse Wave|transverse waves]] consisting of [[Oscillate|oscillating]] [[Electric Field|electric]] and [[Magnetic Field|magnetic fields]] that propagate through space at the [[speed]] of light.
===About Electromagnetic Waves===
*'''Electromagnetic waves (EM waves)''' travel at the [[speed]] of [[Visible Light|light]] in a vacuum, π=3Γ10<sup>8</sup>m/s.
*'''EM waves''' can travel through a [[vacuum]], unlike [[Mechanical Wave|mechanical waves]].
*'''EM waves''' Have a wide range of [[wavelength]]s and [[Frequency|frequencies]], forming the [[Electromagnetic Spectrum|electromagnetic spectrum]].
*Examples include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
*The [[energy]] of an '''electromagnetic wave''' is quantized in packets called [[photon]]s, with [[energy]] propotional to their [[frequency]] with the constant of proportionality being [[Planck's Constant]].
*'''EM waves''' can be [[reflect]]ed, [[refract]]ed, and [[diffract]]ed and as [[Transverse Wave|transverse waves]] they can also be [[Polarized Wave|polarized]].
===Formula===
*πΈ=βπ
Where:
*πΈ is the [[energy]] of the associated [[photon]]
*β is [[Planck's Constant]]
*π is the [[frequency]] of the associated [[wave]]
