What is Maxwells theory of electromagnetism?

Sound & Electromagnetic Waves Definition: Oscillations on the electromagnetic field like radio, UV, Infrared visible light, etc.) n = index of refraction ( in a vacuum n = 1) Frequency always remains constant regardless of medium (although speed changes so wavelength must change too) Math of Sinusoidal Waves Displacement Function (for waves going from left to right): D(x,t) = Asin(2π( xλvt) + ϕ) D(x,t) = Asin(2π(( λ − Tt) + ϕ) D(x,t) = Asin(kx − ωt + ϕ) *if you shift these equations by one wavelength it will remain the same (graphs are with respect to time and Displacement) Other Associated Equations ω = 2π T = 2πf k = 2π λ / / v = λf f = v = 1
