		+	==Key Stage 5==
		+	===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, 𝑐=3×10<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===
		+	*𝐸=ℎ𝑓
		+	Where:
		+	*𝐸 is the [[energy]] of the associated [[photon]]
		+	*ℎ is [[Planck's Constant]]
		+	*𝑓 is the [[frequency]] of the associated [[wave]]
