Physics · Electromagnetic Waves
If the electric field intensity of a uniform plane electromagnetic wave is given as E = -301.6 sin(kz - ωt) ax + 452.4 sin(kz - ωt) ay V/m, then the magnetic intensity 'H' of this wave in A m-1 will be: [Given: Speed of light in vacuum c = 3 × 108 m/s, Permeability of vacuum μ0 = 4π × 10-7 N A-2]
