FIGURE . A linearly polarised electromagnetic wave, propagating in the z-direction with the oscillating electric field E along the x-direction and the oscillating magnetic field B along the y-direction. ω = ck, where, c = / μ ε [ . (a)] The relation ω = ck is the standard one for waves (see for example, Section . of class XI Physics textbook). This relation is often written in terms of frequency, ν (=ω/2π) and wavelength, λ (=2π/k) as c ν λ ⎛ ⎞ ⎜ ⎟ ⎝ ⎠ or νλ = c [ . (b)] It is also seen from Maxwell’s equations that the magnitude of the electric and the magnetic fields in an electromagnetic wave are related as
